What is this? Is this a variable or a pointer?

Because that does not seem OK if defaultdevice is not a pointer.

Also, SegfaultFaultFinding rules apply.

So:
   - full stack frame trace
   - printouts of any relevant variables (at least defaultdevice and aDisplay)

You can use this information to diagnose the problem.
