             Bug #: 57155

           Summary: casting to const reference error

    Classification: Unclassified

           Product: gcc

           Version: 4.7.2

            Status: UNCONFIRMED

          Severity: major

          Priority: P3

         Component: c++

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: rock...@gmail.com





#include <assert.h>

int main() {

    const char* buf = "12345678";

    const int& cref = (const int&)buf[0];

    const int&  ref = (      int&)buf[0];

    assert(cref == ref);

    return 0;

}



// Above assertion failed on g++4.1.2, g++4.4.6, g++4.7.1 and g++4.7.2

// These are all my tested g++ version

// cref just got first byte of buf
