I've been working on a patch to implement that, but I can't manage to
reproduce the false positive from the link.  Maybe the test code I'm
using compiles too fast.  I'm not familiar with -fcompare-debug either.

Could you provide me some code with instructions to reproduce this false
positive, to see if my patch is working as expected?
