           Summary: GCC fails to issue expected error
           Product: gcc
           Version: 4.4.5
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: vanceza@gmail.com

Test case which should not compile

The expected error with the attached test case should be:

test.cpp: In function âint main()â:
test.cpp:18: error: âB::B(const B&)â is private
test.cpp:24: error: within this context

This is issued by versions around 4.2 (not specifically noted; I only have the
mac version of 4.2, and while I had someone verify on another machine I don't
have their exact version info).  However, in GCC 4.4.5, the file instead
compiles, which is correct for the new C++0x standard, but incorrect in C++98.
