@alexfh Are you sure the original crashes were due to https://github.com/llvm/llvm-project/pull/132977 ?

Looking at the patch, it seems unlikely it could cause a crash in itself.

What I think happened is that your compilation proceeded further along and encountered the other crash, which was a regression introduced by a different commit, which had been reported even before that last commit was landed.

It's certainly possible to revert this commit, however there are a lot of dependent patches by this point, and I think this last crash is isolated enough to point into https://github.com/llvm/llvm-project/pull/132401 instead of this commit.
