Hardcore Debugging - Heavy Weapons for Hard Bugs

The article details a challenging debugging scenario involving an Objective-C memory management crash ([PSPDFDocument release] sent to deallocated instance) that occurred only in UI tests with Zombies enabled. The author explains their approach using custom GCD queue wrappers, named queues for better debugging, and DEBUG-mode tracking of all active queues to isolate the elusive bug. It provides technical insights into low-level memory debugging in Objective-C/C++ environments.
