Help with crash???

Can anyone help me understand this crash log? I can't figure out what's crashing and I can't reproduce it in the simulator or on my iPhone, it only happens on my boss' iPhone 4. The project is using ARC if that makes a difference.

Code:
Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0xd8f8c12c
Crashed Thread:  17

Thread 17 Crashed:

That crash log shows no signs of any of your classes. The classes listed are all built in classes. As for the Quartz it may be that it is failing on an animation.

That's what it seems like to me, but why would Quartz be failing on an animation? And why would it only happen on some devices?

Use the analyzer. Turn on Zombies and if needed the various malloc debugging tools. Even though it's crashing in framework code it's almost a certainty that the bug is in your code, somewhere else.

This is true, I would still like to say its in your animation blocks.
