Crash on iOS7, but works fine on iOS6 devices

-1

Team,

I am upgrading the application to iOS7. I am seeing inconsistent crashes in my application when I pushed my app to background and play around with other apps and bring my application to foreground and then perform some actions, it crashes.. I am not able to reproduce the crash without pushing the application to background.

Checking your stack trace exited abnormally with signal 11: Segmentation fault: 11 seems to be the crash

These errors occur when your program tries to access the memory location of an object that no longer exists, an object which at some earlier point in the application's lifetime has had its memory released back into the heap.

If you can track down which variable is being accessed at the time of the crash, through the use of judicious comments or, better still, a debugger, then you will have a potentially easier time fixing the bugs.

In the meantime, re-read Apple's excellent Memory Management guide, which goes into memory management issues in greater detail than can fit into this comment field.
