It appears that the same issue is occurring with jnv. See conda-forge/jnv-feedstock#2. Is this an issue with the clang toolchain? @conda-forge/clang-compiler-activation

h-vetinari · 2024-08-09T07:51:46Z

This seems to be more likely a question of the rust setup to me, as it's happening during rust compilation.

The log

clang-16: error: unable to execute command: Segmentation fault: 11

doesn't tell me anything what failed.

In the jnv failure there's at least one more tidbit:

  = note: ld: warning: directory not found for option '-L$PREFIX/lib'

which could be explained by the fact that the jnv recipe specifies no host environment

I reran the CI for conda-forge/jnv-feedstock#2 and it seems to pass now. Not sure if conda-forge/rust-activation-feedstock#60 had something to do with it. The release notes mention a miscompilation when comparing floats; no idea if that's applicable in the cases above.

Still running into the same on conda-forge/tokenizers-feedstock#70 for the Python 3.8 MacOS build.

h-vetinari · 2024-08-11T09:00:11Z

Still running into the same on conda-forge/tokenizers-feedstock#70 for the Python 3.8 MacOS build.

Interesting that this only happens with py38, that looks like it involves at least one other problem. Since py38 is about to be dropped in 2 month, I'd be fairly liberal in dropping those builds though. 🤷

setu4993 · 2024-08-12T02:50:13Z

With @h-vetinari's help, we got conda-forge/tokenizers-feedstock#70 atleast resolved and merged, but I did see CI fail for MacOS on Python 3.12 atleast once, so I suspect this is likely flaky and maybe broader than just Python 3.8. It could also be caching at some layer for an older image causing it, but I'm not confident.

Should we move this to the rust(-activation) feedstock?

bollwyvl · 2024-08-25T19:22:03Z

Has anyone tried using conda-forge/label/rust_dev to see if it's just a bad version on conda-forge?

0xbe7a · 2024-08-26T16:09:41Z

Has anyone tried using conda-forge/label/rust_dev to see if it's just a bad version on conda-forge?

Yes, Polars is using rust_dev and still experienced this issue when not patching the syn version.

baszalmstra · 2024-09-04T17:55:29Z

Is there any update with regard to this issue? Any workarounds?

bollwyvl · 2024-09-04T18:03:21Z

Thus far have had success downgrading to the MSRV of the upstream, if available/documented/can be inferred from their CI, e.g.:

# conda_build_config.yaml
rust_compiler_version:  # [osx]
  - "1.74"              # [osx]

Some feedstocks (like uv) haven't had any issues with the latest version on main. Without an fruitbox, or a particularly deep knowledge of rust, this is the best I've been able to do.

xhochy · 2024-09-04T19:14:05Z

This only happens with osx-64, not if the build is run using osx-arm64.

Sadly lldb is quite silent:

I was able to poke around a bit. The culprit seems to be the -Wl,-exported_symbols_list,... argument: if I rerun the link step without that argument, no crash.

In my particular sample build of pixi, the contents of that list file are trivial:

___rustc_proc_macro_decls_9059548e8b173a1d__
_rust_metadata_darling_macro_9059548e8b173a1d

(I was able to debug this by manually activating the build environment using build_env_setup.sh, emulating the setup of the recipe build.sh, and then setting $CARGO_TARGET_X86_64_APPLE_DARWIN_LINKER to a one-off wrapper shell script.)

I'll fool around a bit more but it doesn't look like Rust is doing anything incredibly unreasonable here — I think we are uncovering a weird ~~Clang~~ ld crash.

update: Even if the list file is completely empty, I get the segfault. So it looks like the problem is with the fundamental handling of that argument.

Also, if I pass the argument directly without the -Wl, it still crashes.

pkgw · 2024-09-04T19:56:39Z

I was able to attach an lldb to the underlying ld process and identify that the crash is happening in a function ld::passes::order::Layout::Comparer::operator(). I don't know how to use lldb though so that's as far as I'm able to take it (for now).

Web searching doesn't pull up any obvious reports of crashes associated with -exported_symbols_list or this function. So my best guess now is that somewhere in the link line, one of the input files contains some kind of cursed symbol, and that the -exported_symbols_list argument causes ld to scan over all of the input symbols in a way that it wouldn't normally do, causing it to crash.

update: If I use /usr/bin/ld instead of $BUILD/bin/x86_64_apple-darwin13.4.0-ld, there's no crash. I don't understand the toolchain situation well enough to know if that's interesting or not.

update 2: OK, if I reorder the project .rlib dependencies in various ways, the crash goes away?? E.g., if I move the libstrsim-(yadda).rlib dependency just a few slots later in the link list, the manual ld invocation works. Not at all clear to me what's changing.

h-vetinari · 2024-09-04T20:40:03Z

If I use /usr/bin/ld instead of $BUILD/bin/x86_64_apple-darwin13.4.0-ld, there's no crash. I don't understand the toolchain situation well enough to know if that's interesting or not.

That $BUILD/bin/x86_64_apple-darwin13.4.0-ld is packaged here, and it's not impossible that there's a bug in this implementation. I say this because when we briefly enabled "hardened" libcxx builds that trap on certain classes of undefined behaviour (c.f. here), ld ended up failing on osx in some cases. But even if that's the case, it's not clear to me where the error is coming from, and also the most recent version update for that feedstock is stuck.

pkgw · 2024-09-04T20:45:43Z

@h-vetinari I am leaning towards agreeing that it's a bug in this build of ld. I don't see how reordering the input files can cause things to go from "crash" to "no crash" in any non-pathological scenario.

FWIW, the ld that crashes is indeed version ld64-711 from July 2024, according to its -v output. My system version — which doesn't crash — is ld64-609.8 from December 2020. But I note that the newer tool reports using "Apple TAPI version 11.0.0 (tapi-1100.0.11)", while the older system tool reports "Apple TAPI version 12.0.0 (tapi-1200.0.23.5)". I have no idea what TAPI is (and Google reveals absolutely nothing) but I am quite surprised to see the linked version go backwards.

I'm about to wander over to the NumFOCUS project summit so that will be the end of my flailing around today.

h-vetinari · 2024-09-04T22:23:53Z

But I note that the newer tool reports using "Apple TAPI version 11.0.0 (tapi-1100.0.11)", while the older system tool reports "Apple TAPI version 12.0.0 (tapi-1200.0.23.5)".

Indeed, neither do I know what TAPI does (though ld64 is the only package depending on it). I had proposed an update in conda-forge/tapi-feedstock#10 a while ago, which seems to have come to life just now.

isuruf · 2024-09-04T23:41:57Z

TAPI is a library to read .tbd and creating .tbd files from .dylib files.

Hopefully conda-forge/cctools-and-ld64-feedstock#74 changes something 🤞

xhochy · 2024-09-05T13:29:13Z

I have built the linked PR locally and rerun the ruff build, but I still get the same stacktrace:

Has anyone tried if an older ld64 version still works?! It's conceivable that this is a bug in v907 specifically.

mdekstrand · 2024-09-05T21:06:14Z

@h-vetinari FYI this bug is still hitting conda-forge/deno-feedstock#132, even with the new cctools_osx-64 from the PR you linked (I have checked in the build logs to confirm the most recent cctools w/ build number 4 is being used). I also tried bumping the syn version, and that did not fix the segfault either.

pkgw · 2024-09-06T14:07:40Z

In a local test build of pixi, conda-forge/cctools-and-ld64-feedstock#70 fixes the failure for me.

update: in a local test of conda-forge/deno-feedstock#132, the macOS build doesn't succeed, but it gets past the segfault issue in the current version of the PR.

pkgw · 2024-09-06T18:19:54Z

conda-forge/cctools-and-ld64-feedstock#70 has been merged and has propagated. I've retriggered a few sample builds of the Rust projects that were failing and I think they're working now, so hopefully this issue is fixed.

xhochy · 2024-10-13T07:46:47Z

Closing as I haven't seen this in a while. Seems like the fix was sufficient.
