core dumps are turned off by default in /etc/profile. You can make per
user changes by editing your ~/.bash_profile. 

Look for the line, ulimit -S -c 0 > /dev/null 2>&1, you can either
comment out the entire line to set no limit on the size of the core
files or set your own maximum size.

This disables core dumps by setting there maximum size to zero
ulimit -S -c 0. The rest of the line, > /dev/null 2>&1, deletes the zero
length file by redirecting the output to /dev/null.

Instead of using core dumps it would be just as easy to run your
application under gdb.
