clang_complete doesn't complete constructors

Question

Consider this source fragment:

class Z
{
  public:
    Z(int){}
    void foo() {}
};

This works as intended:

int main()
{
  Z a(1);
  a.        // <- at this point, a list of functions appears in a menu

This does not work at all:

  Z b       // <- at this point, nothing happens if I press <Tab> or C-X C-U
            // except a "pattern not found" message
  Z b(      // <- same here

But this does:

  Z b = Z   // a list of constructors appears in a menu when <Tab> is pressed

Is it possible to set up clang_complete such that the constructor completion works in both cases?

This is clang (and libclang) issue, not Vim's plugin clang_complete issue.

clang is now in active development stage AFAIK, so, you can file bug-report at http://llvm.org/bugs . But, I myself filed several bugs related to code completion more than a month ago (e.g. this one) but they are still unresolved.

When I need to get available constructors list, I write code like yours Z b = Z, select constructor, and then convert Z b = Z to something I really need. Not very good, but better than nothing.
