[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.
