At the shell prompt, run "ulimit -c unlimited", then run your application. 
When it segfaults, a file called "core" will be created in the 
application's current working directory, containing the state of the 
application when the segfault occurred.  You can then inspect the core 
file with gdb by running "gdb <myapp> core" where <myapp> is the name of 
the application's binary file.
