EXC_BAD_ACCESS on breakpoint

Hey all,

I have an NSTask thats running a method for me and Im trying to debug why its currently not working. I can go about using my program normally when I select Build and Run, but when I add a breakpoint and select Build and Debug I get an EXC_BAD_ACCESS. Normally this is caused by some sort of deallocation, but Im not dealing with any deallocating objects. Turning on NSZombieEnabled doesnt change anything. The code is as follows
    mainPool = [[ NSAutoreleasePool alloc ] init ];

    NSData *newLines;
    NSString *newLinesString;
    newLines = [[aNotification object] availableData ];
    newLinesString = [[[NSString alloc ] initWithData: newLines encoding:NSUTF8StringEncoding] retain];

    if(![newLinesString isEqualToString:@""])
		{
       NSArray *tempArray = [newLinesString componentsSeparatedByString:@"\n"];
       NSMutableArray *mArray = [[NSMutableArray alloc] initWithArray:tempArray];


I also receive this error just before the call.

If I look at my newLinesString variable in the Locals section, it looks perfect.

Not really sure whats going on here.
Cancelling call - objc code on the current thread's stack makes this unsafe._______________________________________________
