The simulator thinks you've attempted to execute a privileged instruction, 
and threw an exception:

The default reaction was to kill the simulator process. There are two 
problems here:

1) Insight was not notified that an exception occurred. (It would have 
popped up a dialog telling you that an exception occurred.)
2) Either the sim or the executable has a bug concerning this privileged 
instruction. How did you compile your executable (linker scripts, 
libraries, etc)?

I'll look at #1, but #2 may require outside help if it is more than just a 
build error.
