             Bug #: 13273
           Summary: defaulted default ctors + inheritance + const local
                    var == BOOM!
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: eric at boostpro.com

The following trivial C++11 program causes clang to go down in flames.

    struct U
    {
        int t;
        U() = default;
    };

    struct S : U
    {
        S() = default;
    };

    int main()
    {
        S const s{};
    }

$ /usr/local/bin/clang++ -c -O2 -DNDEBUG -std=gnu++11 main.cpp -o main.o
g++: /tmp/main-ubgquK.s: No such file or directory
g++: warning: '-x assembler' after last input file has no effect
g++: no input files
clang: error: assembler (via gcc) command failed with exit code 1 (use -v to
see invocation)

This is with clang build from trunk (recent) on cygwin.
