Why Valgrind

Valgrind is an instrumentation framework that runs your program inside a synthetic CPU and watches every memory operation.

Its most-used tool, memcheck, catches the bugs that crash C programs hours after the real mistake happened.

• Memory leaks
• Use of freed or uninitialized memory
• Out-of-bounds reads and writes
• Bad free / mismatched allocators

C has no garbage collector and no bounds checking. The compiler trusts you completely.

A buffer overflow or a forgotten free compiles cleanly and may even run fine in testing, then corrupts data or crashes in production.

Valgrind gives you the safety net the language refuses to provide.
