--- Comment #1 from tuxifan@posteo.de --- There are 2 issues in this code sample: `STACKFRAME64` isn't zero-initialized, and `SymInitialize` isn't called. Not sure how this is treated, I mean it is literally wrong API usage, but it *is* behaving differently on Windows. I will attach the executable.
