>                 Key: STDCXX-828
>                 URL: https://issues.apache.org/jira/browse/STDCXX-828
>             Project: C++ Standard Library
>          Issue Type: Bug
>          Components: Tests
>    Affects Versions: 4.2.0
>         Environment: Sun C++ 5.9/Solaris/AMD64
>            Reporter: Martin Sebor
>            Assignee: Eric Lemings
>             Fix For: 4.2.1
>
>   Original Estimate: 4h
>  Remaining Estimate: 4h
>
> When compiled with Intel C++ 10.0 on Linux/AMD64 or Sun C++ 5.9 on Solaris 10/AMD64,
the test [27.istream.fmat.arith.cpp|http://svn.apache.org/repos/asf/stdcxx/trunk/tests/iostream/27.istream.fmat.arith.cpp]
abends with SIGABRT. This was observed in 8{D,S}, 12{D,S} and 15D build types, not necessarily
consistently on both platforms.
> The same test was also failing in 4.2.0 with Intel C++.
