Memory debugging tool
'memcheck' provides the ability to fault on pointer overrun (read or write) or freed pointer deference (read or write), logs double free and realloc of already freed pointers and memory not freed on exit, checks for pointer underrun on free and realloc, optionally reverses the behavior of overrun and underrun, "churns" reallocations to always return a different pointer, and logs pointer overruns instead of faulting. It has a very small performance impact, with the tradeoff of a large memory footprint. It includes a validation test suite to verify correctness of the library.
