I have a table view with tall cells. About 300 in height. The cells are custom and have an associated nib. In cellForRowAtIndexPath, I access an object in an array using indexPath.row. The object has properties, which I assign to labels on the custom cell. This works fine for the first two cells. Once I scroll enough for the third cell to get created, the app crashes.

I have NSZombieEnabled set and here is the output:

2010-04-19 21:48:13.360 MyApp[54463:207] *** -[CALayer release]: message sent to deallocated instance 0xfc4e50
(gdb) continue

(gdb) continue
Program received signal:  “EXC_BAD_ACCESS”.

I'm not sure what is deallocated. How can I trace this to the source?
