Hi

If your application causes a segmentation fault, the OS will send it a SIGSEGV signal. When it is running inside Valgrind, Valgrind will see whether or not your application has a signal handler. If not it will print a message describing the fault and also instructions as to what you should do in the unlikely event that the cause is a stack overflow in your program’s main thread.

In short, Valgrind will do the same as you application would do running outsizde of Valgrind, just with a lot more messages.

A+
