Yes, that is odd.  Can you tell me why you think it's executing 0x0?
You could show gdb's side of the conversation, either a console script,
or maybe even include packet traces as per `(gdb) set remote debug 3'.

I don't think so.  The only cache in the pid7t configuration is a little
instruction-decoding cache inside the CPU model, and flushing it just means
throwing it away.  The instruction memory should not be affected at all.
