 Many modern compilers try to detect and warn about this problem, but both false positives and false negatives can occur.Another issue is that heap memory allocation has to be synchronized with its actual usage in any program in order for it to be reused as much as possible.For example, if the only pointer to a heap memory allocation goes out of scope or has its value overwritten before codice_248 is called, then that memory cannot be recovered for later reuse and is essentially lost to the program, a phenomenon known as a "memory leak."
