cocoa app crashes once in a while not reproduceable

Question

I sometimes get a strange error. I do the same thing several times and then sometimes the program just crashes. Most of the time it happens when I try to open a file Dialog or try to determine a random number. I have no idea what it could be. It would be great if someone could point me into the right direction.

Here is the Log I get and an image:

The following happened after the first answers by gaige and Joshua Nozzi:

------------------------------------------------------------------------------------------

I enabled Zombie Objects and when I ran it the first time it told me:

Class _NSZombie_NSIBUserDefinedRuntimeAttributesConnector is implemented in both ?? and ??. One of the two will be used. Which one is undefined.

and

CoreAnimation: warning, deleted thread with uncommitted CATransaction; set CA_DEBUG_TRANSACTIONS=1 in environment to log backtraces.

so I set CA_DEBUG_TRANSACTIONS=1. Could the second warning be because of me running the open dialog in a background thread?

I ran it a few times now and I got several more errors but I can't really see what the problem is and why there isn't always the same error when I perform the same task. I don't expect anyone to actually go through all the error messages (they are more to illustrate my problem) but it would be great if someone could show how I can read and understand them (is there a good tutorial on that?):

Answer 1

For those looking at Error 4's "endUpdates called without a beginUpdates" on a tableview, it may be due to the update of the view (e.g. a [tableview reloadData] call ) occurring outside of the main thread.

See this similar question for more info: NSArrayController rearrangeObjects error

Answer 2

The key here is likely to be in the first line: -[NSMallocBlock openFirstFile:]. In this case, it's clear that the -openFirstFile: message is being sent from the responder to a block that is expected to be something else, but has been reused.

Based on the -[NSControl sendAction:to:] later in the stack trace, this is happening in response to some action (likely clicking the Open button in the standard file window).

In this case, it appears that something is being pointed to by a delegate an IBOutlet and is being released.

I would look at using Zombies (within Instruments, or just enabling them when running normally by using Enable Zombie Objects in the Diagnostics section of the Run area of your Scheme.

Answer 3

This is almost certainly a memory management error on your part. Whatever pointer you're expecting to point to the object to which you send the -openFirstFile: message isn't any more, because that object was released and another now lives at its address - an address you're not supposed to touch because it no longer belongs to your app.

Use Instruments (Zombies instrument) to track down the error.

Answer 4

the bad access error generally occurs when you are trying to reach something outside of range i.e. the 8 the spot of an array of 7. Are you sure this is not the case? This would be my first checking point, making sure you don't exceed the limits :)
