See the attached file - it is modified version of your program. When the
second SIGSEGV occurs SIGSEGV signals are blocked. This is because you
exited the signal handler via a longjmp() and the signal mask is not
cleared. To do what you want you must use sigsetjmp/siglongjmp pair of
calls or remove SIGSEGV from the list of blocked signals.
