The only potential bug I see here is in the error message. What you're seeing is a conflict that arises from D's name mangling. The doSomething in libA is expecting a parameter of type libA.Opaque* and getObject is returning the same, whereas the functions in libB are expecting a parameter of type libB.Opaque*.
It is a bug because even after casting, the compiler gives an error. The compiler wants to know the size of the opaque object, even though I'm dealing with a pointer only. As Maxim Fomin mentioned, the compiler is trying to create an instance of the object even when it is declared as extern (C) and it is a pointer.
