With the tools that come with Valgrind, you can automatically
detect many memory management and threading bugs, avoiding
hours of frustrating bug-hunting, making your programs more
stable. You can also perform detailed profiling, to speed up
and reduce memory use of your programs.
The Valgrind distribution includes five tools: two memory error
detectors, a thread error detector, a cache profiler and a heap
profiler. Several other tools have been built with Valgrind.
Valgrind was ported to FreeBSD by Doug Rabson (http://www.rabson.org/).
