Thanks for reporting the problem @vitalybuka ! 

I don't have a Windows machine to reproduce the issue. It is not clear to me how the IR can contain names like `"??_C at _0BA@MIKMMAII at rawprof?4profraw?$AA@"`. Do we have some special name mangling treatment on Windows?

I will modify the test to check for this string as well, but I will not know the result till the fix lands.
