Uhh, if you declare a struct as dllimport, then you are declaring that it's
vtable is defined in a dll. So why is this a bug?

Of course if you allow compiler to actually inline the virtual function in your
example, the vtable should not be needed. 

Anyway, thanks for reminding me of this bug.  I'll backport 4.4 patch to 4.3.2
once branch reopens.
