The following failures happen with the latest compiler which might be the culprit of the troubles. All binaries segfault:

[ 5403s] The following tests FAILED:
[ 5403s] 	115 - riscv64-ifunc-static-pie (Failed)
[ 5403s] 	202 - riscv64-section-order (Failed)
[ 5403s] 	214 - riscv64-static-pie (Failed)

Binaries:
riscv64.tar.gz

Could you share the entire test directory?

Note I don't have a direct access to the machine, but I need to use xxd to dump the file contents. Please list me files you are interested in?

Export __global_pointer$ from executable
3df7c8e 
RISC-V psABI requires that symbol to be exported from an executable
if there's a GP-relative reference. For simplicity, we always export
it from executable as long as it has a .dynamic section.

The above change may fix the issue. At least it seems related.

Apparently, it hasn't helped with the mentioned commit: https://build.opensuse.org/package/live_build_log/devel:gcc:next/mold/openSUSE_Factory_RISCV/riscv64.
Maybe @andreas-schwab can help you with that?

Ok, so it's addressed with #1206, am I correct? Can you please address also the other tests mentioned in this issue?
