smash the stack: n. [C programming] To corrupt the execution
stack by writing past the end of a local array or other data
structure. Code that smashes the stack can cause a return from the
routine to jump to a random address, resulting in 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. See spam; see also aliasing bug, fandango on
core, memory leak, memory smash, precedence lossage, overrun
screw.
