Gengtype is a mess in frontend processing too. It ignores --enable-languages, parses all the dirs it finds, and expects the types that are defined in multiple frontends, such as lang_decl, to have identical GTY options. Please try adding GTY variable_size option to those lang_decl declarations that don't have it (go, lto, c) If that doesn't help, then on Monday I'll look into this. -- Laurynas
