[Sun C++/Solaris 10/AMD64] 0.strncmp fails subtests in LP64
-----------------------------------------------------------

                 Key: STDCXX-844
                 URL: https://issues.apache.org/jira/browse/STDCXX-844
             Project: C++ Standard Library
          Issue Type: Bug
          Components: Test Driver
    Affects Versions: 4.2.0
         Environment: Sun Studio 12 (Sun C++ 5.9)
Solaris 10/AMD64
            Reporter: Martin Sebor
            Priority: Minor
             Fix For: 4.2.2


When compiled with Sun C++ 5.9 in wide mode (with the -m64 option) the [0.strncmp|http://svn.apache.org/viewvc/stdcxx/trunk/tests/self/0.strncmp.cpp?view=markup]
test fails two subtests. This happens both with 4.2.0 and the head of trunk. No other platforms
seem to be affected. Suspect a compiler bug.
