./x.py test --stage 1  src/test/ui/sanitize/thread.rs

Expected result: Test passes.

Actual result: Test fails with:

Was probably already fixed upstream, see https://reviews.llvm.org/rG8a8fa09cb78af47ad81e933045fc20ddce8482ff. Not sure what the situation for LLVM 13 is.

I can confirm that this is fixed in LLVM 13, it passes for me locally with #87570.

Fixed with the LLVM 13 merge.
