During the execution of a procedural language, one is said to "unwind the stack" from a called procedure up to a caller when one discards the stack frame and any number of frames above it, popping back up to the level of the given caller. In C this is done with "{longjmp}"/"{setjmp}", in Lisp with "{throw}/{catch}". See also smash the stack. [Jargon File] スポンサード リンク
