Update:
Bisecting was not any help. I've gone back several years and the issue(s) are present.
After starting at the core library and working backwards I have narrowed down the
problem to three functions (so far). See the attached patch. This code has largely
been the same for a decade.
I have only diagnosed the RtlConvertSidToUnicodeString() in detail. The problem lies
in the for() loop. Adding a function that involves a static string just above the
for loop negates the issue. Related to the -f-move-loop-invariants optimization. The
wine code has not changed... in 10 years. I will move this discussion to the gcc
list once I can find a smaller reproducer.
