Build fails on OSX 10.15.7

[capital-G]

Currently I am trying to learn Haskell via https://github.com/kowainik/learn4haskell which has happy as dependency for testing.
When I try to run the tests I get the error message

I am pretty new to Haskell so I don't know which infos are relevant and which aren't. If you need some further information, please ask! :)

This does not look like a happy-specific issue. I would try installing GHC with nixos.org/ on macOS. That has the advantage of being strictly reproducible, while whatever error you have looks quite hard to reproduce.

Thanks for the quick advice! I got it working on my machine, see kowainik/learn4haskell#373 (comment)

I am unsure how to perceed here because as haskell novice I can't say what causes the bug - maybe its already fine that the error is written down here with a fix if anyone else has the problem.
