IPhone development - memory issue

I am faced with this problem of releasing an already released object, but I cannot let my life know where the error occurs. I added the NSZombieEnabled flag and this is the log I get in gdb. Can someone please tell me how to solve this problem or rather find out where the error occurred.

*** -[CFString release]: message sent to deallocated instance 0x5e4780

The autostart pool is trying to free an already released object.

This can happen if you manually release the object registered for autorelease

NSString* foo = [NSString stringWithFormat:@"foo:%d",42];  
[foo release];  /* this release is bad, as this object is already 
registered for autorelease */

You can use the following method to find the highlight point:

( ) - "" "". , , malloc_history.
