             Bug #: 12596
           Summary: range-based for (N2930) ignores member access rules
           Product: clang
           Version: 3.0
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: john at mcfarlane.name
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


Observed in Xcode 4.3.2 console project with default debug build
settings/scheme and c++11 dialect turned on. Following C++ program... 

#include <iostream>

class C { int hidden [2] = { 1, 2 }; };

int main() {
    C o;
    for (int n : o.hidden)
        std::cout << n;
    return 0;
}

...compiles and produces output: "12". 

Expected behavior is that compiler produces error such as "'hidden' is a
private member of 'C'".
