Re: Why no crash reporter if I install some signal handler on Leopard



Thanks, all.
I change to install an exception handler rather signal handler with api InstallExceptionHandler(),
and in my exception handler, I firstly invoke some other tool to collect information, and then return -1, so the crash report dialog will be shown. But it still exist a problem: does the InstallExceptionHandler only affect the current thread? If I crash in other thread, will my exception handler be invoked?

The following will work, but it's not ideal:

void sig_abort(int sig)

     abort();
}

It's not ideal because you can't really rethrow the abort with the same stack, you will always show as being in the trap handler (the stack for a crash report looks something like this (on a PPC):

It's also not ideal because printf() is not signal-handler-safe. ;-)

Very true.
