<pre>This program builds fine with "regular" clang, but complains about incomplete
types with -target i386-apple-windows:
$ cat repro.cc
template <typename T> class RefPtr {
T *m_ptr;
public:
~RefPtr() { m_ptr->deref(); }
};
class DeclaredOnly;
class Base {
public:
virtual ~Base();
};
class ReplaceSelectionCommand : public Base {
RefPtr<DeclaredOnly> m_insertionStyle;
public:
virtual void trace();
ReplaceSelectionCommand();
};
void foo() { new ReplaceSelectionCommand; }
$ $C -c repro.cc
$ $C -c repro.cc -target i386-apple-windows
repro.cc:5:20: error: member access into incomplete type 'DeclaredOnly'
~RefPtr() { m_ptr->deref(); }
^
repro.cc:15:7: note: in instantiation of member function
'RefPtr<DeclaredOnly>::~RefPtr' requested here
class ReplaceSelectionCommand : public Base {
^
repro.cc:8:7: note: forward declaration of 'DeclaredOnly'
class DeclaredOnly;
