--- Comment #3 from Sergey Fedorov <vital.had at gmail dot com> --- (In reply to Eric Gallager from comment #2) > possible dup of either bug 60972 and/or bug 68160? >From those topics it looks that the bug, if identical, has never been addressed since GCC 4.9. Would it be helpful to compare against Apple gcc code, which seems to handle the issue correctly?
