Jason Merrill <jason at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu.org --- Comment #3 from Jason Merrill <jason at gcc dot gnu.org> --- This is due to a change for DR 1430 (http://open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#1430), which is still in drafting.
