> Key: STDCXX-93
> URL: https://issues.apache.org/jira/browse/STDCXX-93
> Project: C++ Standard Library
> Issue Type: Bug
> Components: Examples
> Affects Versions: 4.1.2, 4.1.3, 4.1.4
> Environment: Visual C++ 8.0
> Reporter: Vikas Mehta
> Assignee: Martin Sebor
> Fix For: 4.2
> 
> 
> Test case:
> // Following code snippet is taken from examples\manual\time_get.cpp
> // NOTE: A SunPro bug requires time.h preceed locale. PR #26255
> #include <ctime>      // for struct tm
> #include <locale>     // for locale, time_get
> #include <sstream>    // for stringstream
> #include <iostream>   // for cout, endl
> // Print out a tm struct value in one atomic operation
> std::ostream& operator<< (std::ostream &os, const std::tm &t)
> {
> std::stringstream strm;
> strm << "Daylight Savings = "   << t.tm_isdst
> << "\nDay of year      = " << t.tm_yday
> << "\nDay of week      = " << t.tm_wday
> << "\nYear             = " << t.tm_year
> << "\nMonth            = " << t.tm_mon

> << "\nMinute           = " << t.tm_min
> << "\nSecond           = " << t.tm_sec
> << '\n';
> // guard for thread safety and output synchronization
> const std::ostream::sentry guard (os);
> if (guard)
> os.rdbuf ()->sputn (strm.str ().c_str (), strm.str ().size ());
> else
> os.setstate (os.failbit);
