Actually, this thing is more complex to solve than I thought. Specifically, as described in http://www.opengroup.org/onlinepubs/007908775/xsh/stdarg.h.html stdarg requires that variable argument functions have at least one fixed argument. This is implied by the declaration of "void va_start(va_list ap, argN);". As explained in the original ticket description, and also described before in the above link, va_start() must be called before any call to va_arg(), and this includes any access to the argument list using __va_copy namely. The problem is that at least objargs_mktuple(), line 2649 of Objects/abstract.c does not have a first fixed argument.
