memset((void*)0xFFFFFF, ch, 0),non-TICE bzero((void*)0xFFFFFF, 0), andwmemset((wchar_t*)0xFFFFFF, ch, 0)all had bugs that would write to ~16777215 bytes of memory since thesize == 0check would fail when thedstpointer is0xFFFFFF, since(0xFFFFFF + 1) + (0x000000 - 1)doesn't set the carry flag.I have fixed these functions so that they will never write anything when
size == 0.__TICE__ bzeromay still read one byte ifsize == 0, but that should probably be okay.
