----------------------------------------
Key: STDCXX-898
URL: https://issues.apache.org/jira/browse/STDCXX-898
Project: C++ Standard Library
Issue Type: Bug
Components: Tests
Affects Versions: 4.2.1

Priority: Trivial
Fix For: 4.2.2
The 18.numeric.special.int test fails with the following assertions:

Problem is in that the test unconditionally expects that
numeric_limits<>::traps is false for all integral types. Perhaps we need to
hardcode the expected results depending on the platform (as done in
18.numeric.special.float test).
