NSNumber >= 13 won't retain. Everything else will

Question

The code I\'m currently working on requires adding an NSNumber object to an array. All of the NSNumbers with value 0-12 are added fine, but 13 onward causes a EXC_BAD_ACCESS

Answer 1

Clearly NSNumbers >12 will retain. I suggest that you write a very small program that proves this to yourself. Then take that program, make it a function, and call it early in your program. Slowly move the function to later points in your program until the error appears. You will thus find your real bug.
