Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org, | |jason at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think the problem is in build_function_decl_skip_args removing various arguments for a clone, but DECL_LANG_SPECIFIC being copied rather than thrown away. While it takes care to change METHOD_TYPE into FUNCTION_TYPE if the first parameter is being removed, in this case it is preserved, but other parameters removed, and whether they must be there or not is recorded in DECL_LANG_SPECIFIC.
