MS DIA get_virtualAddress for static const class member by pykd team

We have a class:
class TestClass {
    static int a;
    const static int b;
};

When we are parsing a symbol info, we try to get a VA for static member through IDiaSymbol::get_virtualAddress. It return S_OK for both static members. But for const members it returns 0x0 VA.

We tried to print symbol info in windbg ( dt TestClass )
windbg 6.11:
prints right VA for non-constant static member
prints invalid VA for constant static member

windbg 6.2.8220:
prints right address in both cases.
