--- Comment #8 from Richard Henderson <rth at gcc dot gnu.org> ---
Further archaeology suggests that PR 66424 is related,
and had an incomplete fix applied.
The fix for PR 66424 prevents an insn being moved if
it contains a subreg of a multi-word pseudo. But the
same problem exists if one moves a complete multi-word
pseudo if any of its subregs have ever been accessed.
