That fixed it!!

With total reproducibility, from the same source and with all other 
options the same besides DEBUG_THREADS, the version with that build 
option enabled works just fine.  The version built without DEBUG_THREADS 
crashes every time.

I built each three times and carefully checked to make sure I was doing 
the exact same thing in each case.

One thing I noticed is a slight difference on the CLI.
