Variable memory address attribution EXEC_BAD_ACESS

I have an allocated object where its attributes are store in the following memory places: Memory status

When I make a simple attribution of the NSDate attribute to a variable it gives me an EXEC_BAD_ACESS. As you can see from the first image only the date attribute and the fileDate variable have different addresses.

EXEC_BAD_ACESS

Am I making some pointer related error? The other 2 attributes are assigned correctly to the variables, it only happens with the NSDate so maybe I'm missing some detail about NSDate.

Is there any reason why you are not using ARC? There are quite a few memory management errors there causing leaks and one that should cause your crash.

NSDate *dateFromString = [dateFormatter dateFromString:receivedDate];

returns an autoreleased NSDate so when you then call the additional 

[dateFromString autorelease];

you are overreleasing the NSDate hence your crash.

[pFile setDate:[[NSDate alloc] init]];

is a memory leak. Going through the setter setDate: will cause pFile to take a +1 retain on the date, which it should release in it's dealloc. The [[NSDate alloc] init] call returns a date object with +1 but is then never released elsewhere.

You can fix this either with

[NSDate date]

Or

[[[NSDate alloc] init] autorelease];

The first option is preferred
