--- Comment #60 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> --- (In reply to Jonathan Wakely from comment #59) > Should be fixed on trunk, please test and confirm. Confirmed fixed on trunk. Many thanks. Could you please backport to gcc-7-branch and gcc-6-branch? Or okay the backport, which I would be happy to apply.
