using teleop and stoppd responding

[kaloflower]

just got teleop to work, although the inverse kinematics weren't working, the joints and preset locations were working, so i was excited. I hit w again to see if i got the same error in the controller terminal (not teleop terminal), and the teleop terminal stopped responding. I exitted out of everything and tried to open up the controller again, but got an error saying "stack smashing detected" and that all processes on the machine had died. Not sure how to proceed as I have absolutely no idea what went wrong. A side note about why the inverse kinematics weren't working - I believe that it is because we have 3 xl430s, and i was getting an error when i launched the controller - failed to set current based position control model. Any help is appreciated
