More commonly, memory leaks occur in loops where several chunks of memory are allocated, but not all memory is freed. A common one is if you have a dynamically allocated struct containing a pointer to a dynamically allocated string - if you free the struct but forget to free the string, that is a memory leak. A memory leak happens only if the allocated objects can't be garbage-collected because they are referenced from somewhere in the running application. While allocation profiling doesn't tell us anything about the garbage collection, it can still give us hints for further investigation.
