System for determining computer program memory allocation and deallocation

摘要

A system for indicating attempts by a computer program to free memory that is not currently allocated, as well as indicating allocated memory that is never freed. In a particular software program, the programmer includes code that prints a short debug message to a text file every time that a memory allocation or a free-memory operation takes place. After the program completes execution, the text file contains a list of messages indicating all occurrences of memory allocation or free-memory operations. An automated parsing function examines the text file and provides error indications when memory allocation or de-allocation errors are detected.
