Hi Paul,
that's a much nicer reproducer, congrats! And thanks for fixing this regression
so timely. I confirm that all our tests work again with this fix. I guess the
compilation and running with default flags (-g -O2) is not affected by this
fix? But I will test once the fix is committed. 
Nice to hear that you had such a fun time at Calteach. I was never there
unfortunately, but visited Stanford U. and SLAC a lot. And I was lucky to meet
Gell-Mann as well, 2008 in Aspen at the physics center. 
To me the fix looks good to go, when it is pushed I will recompile gcc and run
our code with all different combinations again.
All the best,
   JRR
