Valgrind is an instrumentation framework for building dynamic analysis
tools.  There are Valgrind tools that can automatically detect many
memory management and threading bugs, and profile your programs in
detail.  You can also use Valgrind to build new tools.  The Valgrind
distribution currently includes six production-quality tools: a memory
error detector (memcheck, the default tool), two thread error
detectors (helgrind and drd), a cache and branch-prediction profiler
(cachegrind), a call-graph generating cache and branch-prediction
profiler (callgrind), and a heap profiler (massif).
