I understand that.  There's only two changes in the interval that are
significant (r123630 and r123635 -- r123636 was reverted).  If it's
a latent miscompilation, I still want to know which change exposed
the problem.

The test is failing on both 32 and 64-bit hpux, but not
on linux.  The code generated for the linux target is generally
very similar to 32-bit hpux target and usually miscompilations
appear on both.
