<pre>Unless explicitly defaulted, a trivial default constructor inherited using
C++11's "inheriting constructors" feature is not considered trivial by clang if
the derived class has other constructors.
struct Base {};
struct Derived1 : Base {};
struct Derived2 : Base
{
using Base::Base;
};
struct Derived3 : Base
{
using Base::Base;
Derived3(int) {}
};
struct Derived4 : Base
{
Derived4() noexcept = default;
Derived4(int) {}
};
Derived3 should be trivial but isn't, all other classes are trivial as
expected.
