Bug with decltype and scope operator

Bug with decltype and scope operator


I think I found a bug in the newest release of the Intel Compiler (Composer XE 2013 SP1 Update 1) on Windows; Namely the following code doesn't compile:

void f()
std::vector<int> v;
decltype(v)::iterator i;
int main()
return 0;

This code compiles succesfully with Visual C++, Clang 3.3 (on Linux) and gcc 4.8.2 (on linux).

Yes this is something we just recently implemented in our development compiler.

This is the description of the change:

C++11: decltype allowed in nested-name-specifiers and destructor calls

The resolution of core issue 743, described in n3049, allowing decltype(expr)
to be used in a nested-name-specifier or following "~" in a destructor name is
now implemented.

  template <class T> struct A {
    struct B {};
  template <class T> inline void f(T t) {
    typename decltype(t)::B b;
    T *p = new T();
  int main() {
    A<int> a;

Sorry for the inconvenience.
