again you should consider plct branch or use an older version of gofrontend https://github.com/plctlab/gofrontend
But I can't replicate your issue, so it might not work.

@realqhc , consider the following.

I have a successful build, by using GCC.

I was trying to use Clang compiler.
One of the scenarios lad to a compilation failure.

You can reproduce everything, by using Github Actions.

Hence that Clang's version differ, from case to case. Means we can figure out the minimal required version, to reflect that on gollvm's landing page.

@thanm , if the issue is related to the front-end - why I don't have the same with GCC?

Hence that I have success with Clang 12.

There is a bug within the naming (CMake resolves Clang 12, not 13 - fixing that, right now).
