I am intermittently getting the error below from my application:
Backtrace:

My application has a DTMF input stream as well as a PCM audio output stream. The problem seems to happen after the high level DTMF interrupt handler has been called (it is called from the low level interrupt is a viable DTMF input is detected). I’m not sure if it happens during the handler or after it has exited. I would really appreciate some help with this one. I can use the debugger, but I feel like I just don’t know where exactly to look to determine what is causing the problem.
