--- Comment #5 from Jason Merrill <jason at gcc dot gnu.org> --- Created attachment 54665 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54665&action=edit first try This fixes the PR, but breaks the modules tests that the earlier patch fixed. I guess we need a different fix for the modules issue.
