Latest nightly segfaults with thin lto

[theoparis]

I tried this command:

rustup install nightly --profile complete && cargo install nu

with this ~/.cargo/config.toml:

[unstable]
codegen-backend = true

[unstable.gitoxide]
fetch = true
shallow_index = true
shallow_deps = true
checkout = true
internal_use_git2 = false

#[profile.dev]
#codegen-backend = "cranelift"

[profile.dev]
incremental = true

[profile.release]
opt-level = "z"
lto = "thin"
strip = true
incremental = true

[build]
rustc-wrapper = "ccache"

[target.x86_64-unknown-linux-gnu]
linker = "clang"

I expected a successful install of nushell.

Instead, this happened:

error: rustc interrupted by SIGSEGV, printing backtrace

error: could not compile `nu` (bin "nu")

It seems to have random timing but it seems to be happening every time I run cargo install nu again.

rustc --version --verbose:

I assume I'd have to build rustc and llvm in order to get more backtrace information...

"minimized" to:

RUSTFLAGS="-Copt-level=z -Clto=thin -Cembed-bitcode=yes -Cstrip=debuginfo" cargo +nightly install nu --force --target=x86_64-unknown-linux-gnu

This appears to have been fixed in #130477.
