--- 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.
