--- Comment #2 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
(In reply to Richard Biener from comment #1)
> Possibly related to the asm goto enhancements.

  This test should work only for x86-64.  Running it on other targets can g=
ive
an error.

  So error about inconsistent operand constraints is ok. What is wrong is an
internal compiler error.  The problem is in deleting wrong asm goto in LRA
which results in wrong CFG.

  I've started work on this PR.  The fix will be ready this week.=
