Thank you for the report, this is an LLVM regression that I reported a few days ago and it has now been resolved upstream a few hours ago:

https://github.com/llvm/llvm-project/pull/76552#issuecomment-1878952480 https://github.com/llvm/llvm-project/pull/77236

It may take a few days for it to be fixed on your side between the apt.llvm.org update cycle and the tuxmake container rebuild cycle.

Cheers, Nathan
