<pre>Between the 3.9 branch and ToT the assertion on DeclCXX.h:912 started firing
for this example:
// clang++ -std=c++14 -c test.cpp
struct None {
None() = default;
None(None const&) = delete;
None& operator=(None const&) = delete;
};
template <class Tp>
struct BaseT {
union { Tp __val_; };
BaseT() : __val_() {}
};
BaseT<None> b;
Which results in
<span class="quote">> Assertion `(data().DefaultedMoveConstructorIsDeleted || needsOverloadResolutionForMoveConstructor()) && "move constructor should not be deleted"' failed.</span ></pre>
