             Bug #: 12482
           Summary: Copy constructors of types with members with rvalue
                    references
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: llvm-bugs at quasiparticle.net
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


I don't know exactly whether this is a bug or not, bug g++ accepts it, and I
feel that clang++ should to. Currently, clang rejects this:

struct bar {};

struct tuple {
    struct entry { bar&& member; };

    entry members;

    tuple() : members { bar() } {}

    tuple(const tuple& other) = default;
};

int main()
{
    tuple t;
}

with errors:

% clang++ -std=c++11 -pedantic -ofoo baz.cpp && ./foo
baz.cpp:10:2: error: the parameter for this
      explicitly-defaulted copy constructor is const, but a
      member or base requires it to be non-const
        tuple(const tuple& other) = default;
        ^
1 error generated.
