A further concern is always that heap memory allocation must be synchronized with its real usage in any system to ensure that it to be reused as much as feasible. For example, if the only pointer into a heap memory allocation goes away from scope or has its price overwritten before free() is termed, then that memory cannot be recovered for later reuse and is basically lost to the program, a phenomenon generally known as a memory leak.
