That seems to be correct. In the failing case (when compiled with VS),
the VS debugger lists ntdll.dll and kernel32.dll being loaded before
the crash, and when the executable does not crash, sysfer.dll and
msvcr100d.dll are also loaded. sysfer is a Symantec DLL. Should have
guessed it...

Anyway, thanks for looking at this and sorry to have wasted your time!
