[QUOTE="Stephen Sprunk, post: 5088528"] x86 normally passes all arguments on the stack regardless of type, so bad code often "works". In contrast, x86-64 passes the first several arguments in registers of the appropriate type, so the same bad code "doesn't work" because the callee is looking in the wrong place. Since passing arguments of the wrong type invokes undefined behavior, both are perfectly valid results. S [/QUOTE]
