Farid Zaripov commented on STDCXX-119:
--------------------------------------
It seems that compiler should instantiate the vtable for std::iostream in
testcase object file, but dllimport attribute on B mistakenly brings it to
think, that vtable for base class is also should be imported from external
shared library.
