--- Comment #6 from Gaius Mulley <gaius at gcc dot gnu.org> --- Created attachment 55864 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55864&action=edit Proposed fix Here is a proposed interim patch. In the meantime I'll hunt down the missing case clause (and fix the error location for the original bug). (Although a caveat that I'm currently still bootstrapping on: Linux fedora 6.2.14-300.fc38.x86_64)
