Created an attachment (id=4621)
 --> (http://llvm.org/bugs/attachment.cgi?id=4621)
test case as found in bug

This came up in WebCore.
Simplified test case follows, will also attach.

I believe this may have worked in the past, which would make this a regression.
 But it's also possible the code in WebCore changed since the last time I
compiled this area.


build with 
clang++ -c test.cc
test.cc:12:16: error: incompatible operand types ('Foo const' and 'Foo')
  Foo x = true ? Bar() : Foo();
               ^ ~~~~~   ~~~~~


struct Foo {
};

struct Bar {
  operator const Foo&() const;
};

void f() {
  Foo x = true ? Bar() : Foo();
}
