--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
We used to reject the code with:
k.cc: In substitution of ‘template<class T> void f(typename T::U) [with T =
S]’:
k.cc:8:9: required from here
k.cc:2:6: error: nonnull argument has invalid operand number (argument 1)
void f (typename T::U) __attribute__ ((__nonnull__ (T::i)));
because ARG here:
2818 if (!get_nonnull_operand (arg, &arg_num))
2819 {
2820 error ("nonnull argument has invalid operand number (argument
%lu)",
2821 (unsigned long) attr_arg_num);
used to be const_decl, but since the default_conversion call, it's integer_cst.
