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.

• 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}
