<pre>Compiling OpenSource WebKit with trunk clang fails with errors such as:
Source/JavaScriptCore/API/ObjCCallbackFunction.mm:189:10: error: bad receiver
type 'RetainPtr'
[m_conversionInvocation invokeWithTarget:value];
^~~~~~~~~~~~~~~~~~~~~~
RetainPtr is a reference counted wrapper.
Steps to reproduce:
Compile the following reduction (from Anders Carlsson)
template<typename T> struct RetainPtr {
explicit operator T*() const;
};
@interface A
- (void)b;
@end
void f(RetainPtr<A> a)
{
[a b];
}</pre>
