--- Comment #1 from Iain Buclaw <ibuclaw@gdcproject.org> ---
Considering this a druntime bug.  However I think the proper fix would also involve a compiler change as well.

e.g: In the druntime implementation:

static if (!__traits(isPOD, T))
{
   // Passed by reference...
}
else
{
   // Passed by value...
}

This requires the compiler to pass the objects by invisible reference in the first place.

> Postblit called 6 times

Which is correct - 3 argument copies + 3 copies returned by va_arg. Unless va_arg is supposed to return a *moved* instance of the original argument.
