Can valgrind detect memory corruption?

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.

What is the difference between Valgrind and GDB?

The GNU Debugger (GDB) allows you to pause a running program and inspect its state. Valgrind’s memcheck monitors a program’s memory accesses and prints warnings if the program accesses invalid locations or attempts to read values that the program never set (initialized).

How do I run a program with Valgrind?

To run Valgrind, pass the executable as an argument (along with any parameters to the program). The flags are, in short: –leak-check=full : “each individual leak will be shown in detail” –show-leak-kinds=all : Show all of “definite, indirect, possible, reachable” leak kinds in the “full” report.
