This backtrace doesn't make sense.  If you look at the source code, 
you'll see that if wait_proc is NULL on entry to 
wait_reading_process_output, then line 4677 is never reached.  I'm not 
sure what would cause a bogus backtrace like this.  BLODA?  Optimization?

In any case, I suggest that you wait a week until I have a chance to 
build a pretest of 24.4 for you to try.  I'll build it without 
optimization to make debugging easier.
