Well that's the point of it. Guard malloc specifically tries to crash your app so you can then trace the problem to a problematic allocation and subsequent use. This is a part of what the docs say:

Guard Malloc is a special version of the malloc library that replaces the standard library during debugging. Guard Malloc uses several techniques to try and crash your application at the specific point where a memory error occurs. For example, it places separate memory allocations on different virtual memory pages and then deletes the entire page when the memory is freed. Subsequent attempts to access the deallocated memory cause an immediate memory exception rather than a blind access into memory that might now hold other data. When the crash occurs, you can then go and inspect the point of failure in the debugger to identify the problem.
