Creating a buffer overflow ?

Secondly, once the program has compiled, trying to change a static buffer size to less than it was orignally set to would be very difficult, as if it was a global variable, it would most likely be a space in the exe, and local variables would simply be space on the stack.

Edit: I mean for patching an RSA key or stuff like that.
