>Description:
The compiler gets confused when a member function (static or not) of a template class contains volatile asm.  Attempting to compile the following:

  template <class X> struct test {
    static int foo() {
      __asm__ __volatile__ ("movl %eax %eax");
    }
  };

  int main() { 
    test<int>::foo();
    return 0;
  } 

results in:
