--- Comment #1 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
I can not reproduce it on today trunk. I guess it was fixed by some LRA patch
but I ca not say by what patch exactly as there were too many LRA patches since
May.

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Likely fixed by r199764 (r199763 fails, r199769 works, no other commits that
could affect i?86/x86_64), likely introduced by r199298 (works r199200, fails
r199300).
Vlad, is there anything needed but to include the testcase into the testsuite
(will test it in the next bootstrap/regtest cycle)?
