Summary: Fake ambiguity between scoped redeclaration of class
found via inline anonymous namespace
Product: clang
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: C++0x

// scoped declaration fails (correctly: [namespace.qual]p7) if namespace isn't
inline
// works if namespace isn't anonymous
inline namespace {
class A;
}
// if not scoped, ambiguity is real, no bug
class ::A {};
A a;
