I'm using cocos2d and I load all my sprites and scenes before my game. However, once loaded, it seems if I click to start the game too quickly I get this crash:
malloc: *** error for object 0x65cdbb4: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
So I did what it suggested, recreated the crash and the stack shows this:
#0 0x9033df7e in malloc_error_break ()
#1 0x9033f128 in szone_error ()
#2 0x9033f29b in free_list_checksum_botch ()

I am getting these crash reports on Xcode organizer from users of the app. It does not show any line of my code in the crash, looks like it crashed on init. I do not know how to progress with the debug. Can you please help:

I had a similar issue. In my case, the issue was that I changed the watch app extension name, so it doesn't include the underscore character. After this, I experienced this crash.
The solution was, to go into the storyboard file of the watch app extension, and in the identity inspector of the existing view controllers, I just retyped the name of the custom class names, and the module updated automatically. After this, it worked. Hope it works for you as well.
Just FYI. The issue that I had was one of those embarrassing ones.
The storyboard had "Inherit Module From Target" on.
However, the default layout that Apple creates, has the executable in a separate (Extension) target.
I need to uncheck that box, and explicitly reference my extension target.
D'oh!
When I try to run the Perl debugger I'm getting a SEGV error:
Signal SEGV at /opt/csw/lib/perl/csw/Term/ReadLine/Gnu.pm line 240.
Term::ReadLine::Gnu::new("Term::ReadLine", "perldb", GLOB(0x81c1168), GLOB(0x81873a0)) called at /opt/csw/share/perl/5.10.1/perl5db.pl line 6073
DB::setterm called at /opt/csw/share/perl/5.10.1/perl5db.pl line 2237
DB::DB called at -e line 1
Abort (core dumped)
The errors takes place with any Perl code and I think is due to the debugger using Term::ReadLine::Gnu::new.
Using gdb to get the stack trace, I get the following:
Core was generated by `/opt/csw/bin/perl -de$a++'.
Program terminated with signal 6, Aborted.

Very infrequently, our app is crashing because it receives SIGKILL. The circumstances are different, but the backtrace is always the same:

#22 0x000027c5 in start ()
How would I go about finding out what is causing this crash?
The SIGKILL is sent to apps for any kind of exceptions. Se we have to make an educated guess what the exception reason would be in this case. In the above case it looks like accessibility is checking for a certain kind of pasteboard type to be present.
Since this is happening in Apple code most likely this is a bug in iOS, because the containsPasteboardTypes: method should never throw an exception. Only possibly if the passed parameter is nil, but then the bug would lie in UIAccessibilityTextFieldElement which too is Apple's responsibility.
Long story short: you need to file a radar. As a workaround you can add an #try block around the offending operation. This would catch and ignore the exception.
My app crashes only in simulator , it doesn't crash on device.
it crashes in simulator and gives me nothing except this :

Why is this happening?
Thanks.
Set NSZombieEnabled, MallocStackLogging, and guard malloc in the debugger. Then, when your App crashes, type this in the gdb console:
(gdb) info malloc-history 0x543216
Replace 0x543216 with the address of the object that caused the crash, and you will get a much more useful stack trace and it should help you pinpoint the exact line in your code that is causing the problem.
See this article for more detailed instructions.
Another idea is to try turning off auto-correction in the simulator Settings App.
