--- Comment #1 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
Thank you for reporting this.  I am trying to find the best place to fix this:
either in memory subreg elimination or in match_reload itself.  I hope the fix
will be ready tomorrow.

There are no complaints about the patch for more a week.  So I guess the PR can
be closed.
