No information there. I need a valgrind output when the program crashes.

When the program does an illegal memory access, valgrind does not necessarily 
stops it as the kernel does. It ignores it, displays the error, and tries to 
continue. When it really cannot continue, it stops and dumps a "vgcore" file.

You must find a way to reproduce the crash, and then run valgrind to get the 
information on it.
