--- Comment #1 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
Andreas, thanks for the analysis.  The rematerialized insn should be not a
candidate.  A check exists for this in la-remat.c but still it happens.  I'll
investigate this more on Monday and definitely fix it on the next week as this
is a serious problem.
