    Hi! :wave: 

I'm not sure how I should properly report the issue, but I've been asked to *PLEASE submit a bug report*, so here.

I'm running the build using Nixpkgs, if it helps, the commit where this can be observed:

 - https://github.com/samueldr/nixpkgs/commits/b1677af8e5ed26a41d337ac3fbabd8c27ea5251a

Using this command:

```
 $ nix-build -A pkgsCross.x86_64-unknown-uefi.lanzaboote-uefi-stub
```

The complete build log (for compiler-rt, where the crash happens) is here:

 - https://gist.github.com/samueldr/9e2052318b1601a1400a672ceaa3668b

The two files are also attached to the gist.

Do ask if I can provide anything else!
