Help with SIGSEGV error, please?

Question

Greetings,
I have no idea what this error log means. It only happens on one computer, so it isn't the program. Something in the system is messed up. Can anyone tell what from this?
# A fatal error has been detected by the Java Runtime Environment:
#  SIGSEGV (0xb) at pc=0x00007fff840542db, pid=533, tid=36871
# JRE version: 7.0_10-b18
# Java VM: Java HotSpot(TM) 64-Bit Server VM (23.6-b04 mixed mode bsd-amd64 compressed oops)
# Problematic frame:
# C  [libGL.dylib+0x22db]  glGetString+0xf
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

And where do I type "ulimit -c unlimited"? I typed it in Terminal, but nothing happened.
Thanks

Hi, I�m currently writing some code that requires me
to read in a list of names and prices from a txt file
then sort them, I have so far successfully created a
menu and the code to read in my txt file "cars.txt"
however it is returning me with an error, I need to
sort this part out before I can move on to the
sorting section, any help would be much appreciated,
