failmalloc

The idea behind failmalloc is to demonstrate what really happens if memory allocation fails. Unfortunately, most programs in this world are not robust, mostly because programmers are careless, but sometimes because programmers are too brave. Regardless of whatever reasons, the most critical problem is in that there is no good way to see such failures in reality, until a program is deployed into a heavy production system. Clearly, this is too late! Failmalloc addresses this problem. Failmalloc inserts hooks into your program, which induces always, often or sometimes failures of memory allocation calls. The functions malloc, realloc and memalign are hooked, but other functions which use one of these functions are also affected.
