Memory Allocation Checker 0.2.1

Memcheck provides the ability to fault on pointer overrun or freed pointer deference.
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. It is tested on a variety of architectures, including Alpha, ARM, HPPA, PPC, ix86, IA64, rs6000, S390, SPARC, and SPARC64.

It is tested on a variety of platforms, including OSF, FreeBSD, NetBSD, OpenBSD, Linux, HP/UX, Mac OSX, AIX, SCO, and Solaris.

What's New in This Release:

Some missing backtraces were fixed.
An atexit replacement was implemented to catch allocations that are freed by previously installed atexit handlers.
Deeper backtraces are stored, and internal recursions are handled.
