<pre>
    I am packaging LLVM 16.0.0rc4 for [NixOS](https://nixos.org) and I am running into one unique failed test on x86_64 at the moment which is tools/gold/X86/parallel.ll.

More generally, it seems like `LD_PRELOAD=LLVMGold.so` for any non trivial program will make this program crash, more logs are here:
```

I wanted to understand if this is something that maintainers have already encountered or whether I should investigate more with debug builds and all.

Thank you in advance!
