--- Comment #6 from Paul Thomas <pault at gcc dot gnu.org> --- Created attachment 42733 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42733&action=edit A partial fix for the PR This fixes the testcase and, indeed, some more elaborate versions. However, coarray_allocate_5.f08 with the type 'foo' declared in a module offends gimple horribly. It appears that the vtable is completely screwed up such that accessing 'copy' gets 'def_init' instead. That said, this does at least regtest OK. Paul
