Sample example program to get the malloc consolidate error

Sample example program to get the malloc consolidate error

I want to test the mcheck functionality on my PC first to detect the
malloc consolidate error. This way, i will be sure that this will help to
figure out a similar crash on embedded-linux box. Unfortunately, the crash
takes atleast 3-4 days. Thus, I am looking for a sample program that will
generate the similar kind of crash as shown below.
Program terminated with signal 6, Aborted.
