Thanks Alina to analyze the problem and write the fix.

I agree with your analysis and I believe the patch could fix the problem. But I am little worried the blunt hammer fix could pontentially hurt performance.  Maybe we can use MD to do a finegrain check? I draft a fix attached. Please take a look whether it is correct and free to change it. F9879631: patch <https://reviews.llvm.org/F9879631>
