I want to test how well our background agent is restarted. I'd
like to programmatically induce a crash. What's a good way to do
so?
I'm not certain if you mean crashing use a Cocoa method, but this
should certainly cause a memory fault crash.
int *x;
x = 0;
*x = 5;
Yeah, something like that. I didn't know if there was a more
preferred way.
abort() and __builtin_trap() work well. They have the advantage of
being grep-able when you want to take them out. abort() and
__builtin_trap() and intentional memory faults should behave
identically other than the precise contents of the crash log, unless
you have signal handlers for SIGSEGV/SIGBUS/SIGABRT.
Hmm. Good to know. We may have *some* sig handlers, but this is just
for testing in one place (-(void) crash: (id) sender)).
Thanks!
