--- Comment #4 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
I've reproduced it and started to investigate. It is a very complicated
example.  I can not even say right now what is wrong, the check or the
allocation result.  I guess it will take some time only to investigate it.  In
the best scenario, it will be fixed on this week.
