A.1.5 MemoryChecking.c Applications which use dynamic memory management (malloc / free) must ensure that all malloc’d memory blocks are freed after use. If allocated memory is not freed, then that memory is no longer available for re-allocation to the program, thus reducing the total available memory.

These errors will not cause the application to fail, and are composed of completely legal C statements. Program errors such as these are easy to create, can manifest themselves unpredictably, and are difficult to reproduce and debug.
