smash the stack

[C programming] n. On many C implementations it is possible to corrupt the execution stack by writing past the end of an array declared `auto' in a routine. Code that does this is said to `smash the stack', and can cause return from the routine to jump to a random address. This can produce some of the most insidious data-dependent bugs known to mankind. Variants include `trash' the stack, scribble the stack, mangle the stack; the term *mung the stack is not used, as this is never done intentionally.
