   It really makes no sense to check for a zero PC here.  This function
   is only colled from frame.c:get_prev_frame(), and there we already
   deal with PC being zero.

   [...]

   Objections.  Otherwise I'll commit this within a few days.

	   * blockframe.c (inside_main_func): Don't treat a zero PC specially.
	   Needed to fix PR backtrace/1476.

I've checked this in now.
