I'm almost certainly betraying my ignorance here, but it sounds to me like malloc isn't doing any sanity checking to make sure that the memory it received isn't already being used. Well, malloc doesn't receive memory, it allocates it, and PyMallocDebugMalloc just wraps somebody else's malloc. It's not trying to debug the platform malloc, it's trying to debug "the user's" (Python's) use of the memory malloc returns.

Okay, you really meant it when you said that your debug wrapper doesn't touch the underlying malloc() implmentation. ;-)
