--- Comment #11 from Andrey Belevantsev <abel at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #10) > Fixed on the trunk so far. FWIW I stared at the code for some time but couldn't devise anything better than your patch. The hunk itself is somewhat suspicious as Alex said, and he wanted to experiment with removing it altogether and looking at how it influenced the -fcompare-debug. But I doubt it would make any difference.
