--- Comment #31 from Christian Häggström <gcc at kalvdans dot no-ip.org> ---
What you describe Sandra is mentioned in the man page for longjmp(3). Maybe we
can steal some of its documentation.
Caveats
If the function which called setjmp() returns before longjmp() is
called, the behavior is undefined. Some kind of subtle or unsubtle
chaos is sure to result.
