--- Comment #3 from Thomas Bernard <thomas at famillebernardgouriou dot fr> ---
I tried investigating this and it seems that decltype( v1 = v2 )::t1 should be
handled as a dependent type, but isn't. I modified the test case like this

template <typename T>
void f1(typename decltype(v1 = v2)::t1);

and the problem seems to be solved.
