--- Comment #11 from Vladimir Makarov <vmakarov at gcc dot gnu.org> --- (In reply to Christophe Lyon from comment #10) > Hello Vladimir, > Have you been able to make progress on this bug? Thanks for the remainder, Cristophe. Sometimes I am loosing track of bugs I should work on as I have to many of them. I checked gcc-4.9-branch and the test. I believe the patch mentioned for rev. 215707 is the right solution. It could be a bit different but it has no sense to try something else as the patch had already good testing and proved by time. So you can submit the patch into gcc-4.9-branch after standard procedure (bootstrap at least on x86-64 and aarch64 and testing on the both platform). I approve it.
