That's my primary (only?) hypothesis, too, but it still seems very weird
that the "alternate" results only show up in this one very specific case
(one invocation method on one machine).   It seems like if it really was a
stack size/alignment issue that we'd be seeing inconsistent results on more
than one machine.
