I'm not entirely sure what the original intent of this statement was, but the effect ends up being that some codeloc entries end up negative in the compressed representation, but the code always assumes unsigned integers, so things roundtripped badly, leading to badly corrupted stack traces. I guess this might have been a rebase mistake,
since the same line exists (correctly) a few lines prior. Fixes #54031.

Yeah, I don't know why it looks like there ended up being two copies of this line
