How Do You Use Valgrind

Valgrind Memcheck is a tool that detects memory leaks and memory errors. Some of the most difficult C bugs come from mismanagement of memory: allocating the wrong size, using an uninitialized pointer, accessing memory after it was freed, overrunning a buffer, and so on.

How is valgrind used for debugging?

Valgrind recompiles binary code to run on host and target (or simulated) CPUs of the same architecture. It also includes a GDB stub to allow debugging of the target program as it runs in Valgrind, with “monitor commands” that allow querying the Valgrind tool for various information.
