[jira] Created: (STDCXX-212) [MSVC 6.0] std::has_facet,
std::use_facet broken
[MSVC 6.0] std::has_facet, std::use_facet broken
------------------------------------------------
Key: STDCXX-212
URL: http://issues.apache.org/jira/browse/STDCXX-212
Project: C++ Standard Library
Type: Bug
Components: 22. Localization
Versions: 4.1.2, 4.1.3
Environment: MSVC 6.0
Reporter: Martin Sebor
Moved from the Rogue Wave bug tracking database:
****Created By: sebor @ Jun 16, 2004 12:17:37 PM****
The example manual/hasfacet.cpp prints 'false\nfalse\n' when compiled with MSVC 6.0. This is due to the interaction of two bugs: PR #27947 and PR #28102 which prevents has_facet from using the workaround mentioned in PR #27947 (using the default argument). This effectively means that std::has_facet and std::use_facet are pretty much useless.
#include <ios> // for boolalpha
#include <iostream> // for cout, endl
#include <locale> // for has_facet()
#include <examples.h>
// dummy facet, must derive from locale::facet
// and define a static member of type locale::id
struct my_facet: public std::locale::facet
{
static std::locale::id id;
};
std::locale::id my_facet::id;
int main ()
{
// see if ctype<char> is contained in the locale imbued in cout
std::cout << std::boolalpha
<< std::has_facet<std::ctype<char> >(std::cout.getloc ())
<< std::endl;
// see if my_facet is contained in the locale imbued in cout
std::cout << std::has_facet<my_facet>(std::cout.getloc ())
<< std::endl;
return 0;

[jira] Closed: (STDCXX-212) [MSVC 6.0] std::has_facet,
std::use_facet broken

Martin Sebor closed STDCXX-212.
-------------------------------
Resolution: Won't Fix
MSVC 6.0 is so old and broken that it's not worth our effort to worry about it. In addition, more recent versions of the compiler handle the code fine so an easy solution is to upgrade.

Posted by "Martin Sebor (JIRA)" <ji...@apache.org>.

Martin Sebor updated STDCXX-212:
--------------------------------
Priority: Minor (was: Major)
Lowered priority since the problem can be dealt with by upgrading to MSVC 7.x and 8.0.
