template<typename> class vector { };
struct A{};
template <class T1>
void complete_test(vector<T1> data1){
        A drop=A();
}
int main(){
  vector<double> vect1;
  complete_test(vect1);
}

Fine with -std=c++98 but not with -std=c++0x:
bug.cpp: In function ‘void complete_test(vector<T1>) [with T1 = double]’:
