Re: how to crash on normally ignored exceptions

I have found those rather flaky as well in the new dev tools...

A work around, which is made quite difficult because classes apparently
are not registered as symbols in the debugger, is the following:

(gdb) p (void*)NSClassFromString(@"NSException")
$1 = (void*)0xa07ed448
(gdb) p (void*)[$1 instanceMethodForSelector:@selector(raise)]
$2 = (void*)0x90844888
(gdb) b *$2
Breakpoint 1 at 0x90844888

Could someone from Apple comment on the poor handling of symbolic
debugging, especially related to Objective-C, in the current gdb/dev
tools suite? The question may be better suited for the pbdev mailing
list - I am sorry...

/ Sincerely, David Remahl
