A common trick I use if I want to dump core when an exception is
triggered is to simply override -raise as follows:
@implementation NSException (CoreDumps)
- (void) raise
{
abort ();
}
@end
Afterwards, simply enable core dumping if you're on Linux and run your
program:
$ ulimit -c unlimited
$ ./myprog
