Valgrind

Valgrind is a suite of tools for profiling software:


 * Memcheck detects memory issues (leaks, accessing invalid memory, deallocating memory more than once, etc.)
 * Cachegrind profiles CPU cache misses, a possible optimization opportunity
 * Callgrind is an extension to Cachegrind with more information
 * Massif profiles memory heaps for performance issues
 * Helgrind detects multithreading race conditions
