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.
