Well not exactly (UNIX systems protect memory properly).
From the man page...
DESCRIPTION
crashme is a very simple program that tests the operating
environment's robustness by invoking random data as if it
were a procedure. The standard signals are caught and han-
dled with a setjmp back to a loop which will try again to
produce a fault by executing random data.
