While reducing a miscompilation, something broke in bugpoint:

Checking to see if the program is misoptimized when this function is run
through the passes: hypre_SMGRelaxSetupASol
<cbe><gcc><llc><gcc><program>: still failing!

*** The following function is being miscompiled:  hypre_SMGRelaxSetupASol
Extracted a loop from the breaking portion of the program.
<cbe><gcc><program>  *** ERROR: Loop extraction broke the program. :( Please
report a bug!
      Continuing on with un-loop-extracted version.
Please submit the bugpoint-loop-extract-fail-*.bc files.

This is on x86-64 Linux.
