--- Comment #6 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- It's a bad interaction between closures and variadic functions (and the other test cls_longdouble_va.c passes by accident), which will require the SPARC-V9 code to define FFI_TARGET_SPECIFIC_VARIADIC. I'm a bit surprised that only ARM and PowerPC define it at the moment.
