I am currently programming a iPhone-app for my maturity research. But there is an behavior I don’t understand: Sometimes when i compile my project there is:
Thread 1: Program received signal : “EXC_BAD_ACCESS”.
But when I compile the same code a second, or a third time the code just runs fine and i can’t get why. I use some MonteCarloSimulation but when it fails it fails executing one of the first 100 simulations. But when every thing runs fine it executes 1000000 simulations without an error.. Really strange isn’t it?
Do you have any idea? Can this be an issue of Xcode or arc?
All other things just work perfect.
Do you have to get any further information? I can also send you my code as an email.
This usually means you’re trying to access an object that has already been deallocated.
In order to debug these things, Objective C uses something called “NSZombie” that will keep those objects around so you can at least see what it is that’s trying to be called. See this question for some details on how to use it.
