--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 45894 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45894&action=edit gcc9-pr88568-2.patch Untested fix for that. Apparently the C++ FE relies that static data members have TREE_STATIC set, even when they are DECL_EXTERNAL, so this patch essentially reverts the previous patch for static data members. Unfortunately, like before, I have no way to test this on mingw/cygwin etc.
