Target Milestone: ---
r244608 with -std=c++1z fails to compile this program both with and without
-fno-new-inheriting-constructors:
struct base {
base(int, int) {}
};
template<class>
struct derived : base {
using base::base;
};
int main() {
base(13, 42); // Fine
derived<int>(13, 42); // Fine
base{13, 42}; // Fine
derived<int>{13, 42}; // Error
}
with diagnostics:
prog.cc: In function 'int main()':
prog.cc:14:22: error: too many initializers for 'derived<int>'
derived<int>{13, 42}; // Error
^
prog.cc:14:22: error: could not convert '13' from 'int' to 'base'
