The abort() first unblocks
the SIGABRT signal, and then
raises that signal for the calling process. This results in
the abnormal termination of the process unless the
SIGABRT signal is caught and
the signal handler does not return (see longjmp(3)).
If the abort() function
causes process termination, all open streams are closed and
flushed.
If the SIGABRT signal is
ignored, or caught by a handler that returns, the
abort() function will still
terminate the process. It does this by restoring the default
disposition for SIGABRT and
then raising the signal for a second time.
