--- Comment #10 from janus at gcc dot gnu.org --- (In reply to Ondřej Čertík from comment #9) > Janus, thanks a lot for fixing this! You're welcome! > Yes, it's part of a large code base. I'll try the trunk soon. That would be great. Since this bug is a regression, I plan to backport the fix to the 4.8 and 4.9 branches. But before that it would be good to make sure that no further problems appear. I think the NON_OVERRIDABLE attribute is not incredibly well-tested at this point.
