--- Comment #6 from Paul Thomas <pault at gcc dot gnu.org> --- Created attachment 37531 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37531&action=edit Fix for 5-branch 5-branch requires a slightly different fix. For some reason, the argument to copy is not being given the unlimited polymorphic attribute. Even the symbol doesn't have it. Logically, the only way that a character can be copied to a class object is that it is unlimited polymorphic and so the requirement is ignored in this case. My inclination is to commit this patch to 5-branch since it regtests OK and is minimalist. Cheers Paul
