>Description:
When doing ptype on a templated class, GDB will print
out constructors as having a return type of void
instead of as having no return type at all.
>How-To-Repeat:
Compile this:

template <typename T>
class C {
public:
  C() {}
};

class D {
public:
  D() {}
};

int main()
{
  C<int> c;
  D d;
}
