<pre>The following code gives 'error: cannot compile this non-trivial argument copy
for thunk yet' when compiling with clang-cl. Interestingly enough, the
inheritance from F is required to trigger the problem. Just have a destructor
for F instead of JavaScriptChild does not trigger the problem
class A {
A(A &);
};
class B {
virtual int *m_fn1(int *, A);
};
class C : virtual B {};
class D : virtual B {
int *m_fn1(int *, A);
};
class F : D, C { };
class JavaScriptChild : F {
~JavaScriptChild();
};
JavaScriptChild::~JavaScriptChild() { ; }</pre>
