You wouldn't.  A memory leak, in a nutshell, is a call to malloc() without a 
corresponding call to free() sometime afterward.

It'd be approximately impossible to deterministically tell from the outside 
whether a program is truly leaking memory, or whether it was simply 
delaying the free() call until some later time.  If have access to the 
program's internals, you can probably get a much more accurate answer.
