MSVC responce:
error C2664: '__thiscall B::B(const struct B &)' : cannot convert parameter
1 from 'const struct A<struct C>' to 'const struct B &'
        Reason: cannot convert from 'const struct A<struct C>' to 'const
struct B'
        No constructor could take the source type, or constructor overload
resolution was ambiguous
see reference to function template instantiation '__thiscall A<struct
B>::A<struct B>(const struct A<struct C> &)' being compiled
