SIGSEV is a signal, not an exception. No exception handling code will do 
anything with it. And pure c code _can't_ throw exceptions of any kind, 
because C has no exceptions (it _might_ be possible for an exception to come 
out of C code which called code from another language which _does_ have 
ecxeptions, but I'm not sure). If you want to handle SIGSEGV, you need a use a 
signal handler.
