  Yep, and it even works (or rather, doesn't work) if you make foo a local
variable.  And it goes wrong at -O2 as well as -O3.  But -fno-loop-optimize
stops it.

  I guess it just goes to show that a dynamically-varying loop bound is a
pretty rare programming idiom, or people would have run up against this more
often before.......
