valgrind

Wrapper for a set of expert tools for profiling, optimizing and debugging programs. Commonly used tools include memcheck, cachegrind, callgrind, massif, helgrind, and drd. More information: http://www.valgrind.org.

  • Use the (default) Memcheck tool to show a diagnostic of memory usage by program:

valgrind {{program}}

  • Use Memcheck to report all possible memory leaks of program in full detail:

valgrind --leak-check=full --show-leak-kinds=all {{program}}

  • Use the Cachegrind tool to profile and log CPU cache operations of program:

valgrind --tool=cachegrind {{program}}

  • Use the Massif tool to profile and log heap memory and stack usage of program:

valgrind --tool=massif --stacks=yes {{program}}
