Yes, in fact that's *exactly* what GCC is assuming. And it will be true for all code that GCC generates. > Also, when you say "stack going into main is 16 byte aligned", > what specifically do you mean? That the first argument to main is 16-byte aligned. This implies that the return address from main is at addr % 16 == 12. If you're able to fix this in your OS, don't forget to do the same with the pthread entry function and signal handlers. r~
