Yes, but like I mentioned it's an intermittent problem, happened only
once in the office and 50%+ of the time in the field. Further, before
the end of main() we have a while(1) {...} loop for our control logic.

Either way, Francois Theron will be continuing this thread. He is my
colleague, the design engineer who is in charge of this project. I
will still be following it though. So if you see responses from either
of us it's for the same problem.

Further, he confirmed that the MCLR is used as a programming PIN. I'm
not sure if that is an open input/output. We are performing tests on
this now.
