  To address this, you'd need to first isolate the problem to a smaller
  test program, with only a small number of gmp calls, and no dependency
  on mpc. And in that process you will likely find out if the problem is
  in mpc or in gmp.
I suppose the place to start is to run the supposedly passing test
variant a few dozen times and see if that too cannot be made to fail,
then similarly run the failing test to see if it fails always.  This
will give some hints about whether it is hardware problems; test
outcomes should be reproducible on stable hardware.

I assume you've run GMP's own testsuite for both builds.  If either
fails, you've likely detected a problem with the compiler, assembler,
linker or some system library.  A GMP problem being the culprit for any
failure here is exceedingly unlikely since we've of course run the
testsuite for your CPU time before we made the release.
