--- Comment #24 from Vladimir Makarov <vmakarov at gcc dot gnu.org> --- (In reply to Richard Biener from comment #23) > Vladimir, can you look into this LRA inheritance issue? Yes, I've started to work on this. I can not reproduce it on the current trunk. But yesterday, I've reproduced it on the revision mentioned in the title. Inheritance problems are usually hard to fix. So I can not say when I find a reason for the problem and solution for it. But I guess it will be fixed on the next week.
