--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> --- Created attachment 37483 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37483&action=edit Proposed patch. Attaching a proposed patch tested on x86_64-linux. Since GCC is in stage 4 (regression fixes only) and this is no a regression it will probably have to wait until after the 6.0 release.
