           Summary: Assert when compiling - "Access specifier is AS_none
                    inside a record decl"
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs@nondot.org
        ReportedBy: ori@avtalion.name
                CC: llvmbugs@cs.uiuc.edu, dgregor@apple.com


The following piece of code compiles with g++, but doesn't with clang++

struct Foo {
    template<class A>
    struct IteratorImpl {

        template<class T> friend class IteratorImpl;

        IteratorImpl() {}

        template<class T>
        IteratorImpl(const IteratorImpl<T> &c) {}

    };

    typedef IteratorImpl<int *> iterator;
    typedef IteratorImpl<const int *> const_iterator;

    iterator end() {
        return iterator();
    }
};

Foo foo;
Foo::const_iterator iter = foo.end();

===================================

clang: DeclBase.cpp:463: void clang::Decl::CheckAccessDeclContext() const:
Assertion `Access != AS_none && "Access specifier is AS_none inside a record
decl"' failed.
