[HP-UX 11.23] std::num_put drops sign from negative long double NaN
-------------------------------------------------------------------

                 Key: STDCXX-464
                 URL: https://issues.apache.org/jira/browse/STDCXX-464
             Project: C++ Standard Library
          Issue Type: Bug
          Components: 22. Localization
    Affects Versions: 4.1.3
         Environment: HP-UX 11.23 and prior
            Reporter: Martin Sebor
            Assignee: Martin Sebor


On HP-UX 11.23 and prior versions of the OS negative long double NaN is formatted without
the minus sign:

$ uname -sr && cat t.cpp && nice gmake t && ./t
HP-UX B.11.23
#include <cassert>
#include <iostream>
#include <limits>
#include <sstream>

int main ()
{
    std::ostringstream os;
    os << std::numeric_limits<double>::quiet_NaN () << " == "
       << std::numeric_limits<long double>::quiet_NaN () << '\n'
       << -std::numeric_limits<double>::quiet_NaN () << " == "
       << -std::numeric_limits<long double>::quiet_NaN ();

    std::cout << os.str () << '\n';
    assert (os.str () == "nan == nan\n-nan == -nan");
}
