There was a commit in the main trunk:

Fixes to locale code to properly use indirect pointers in order to prevent
memory leaks (fixes bugs earlier purported to be fixed).
Submitted by:   Ed Moy <emoy at apple.com>
Obtained from:  Apple Computer, Inc.
MFC after:      2 weeks
----

RELENG_4 is still waiting for MFC.

This is important, since STL depends on correct locale switching.
Each int-to-string STL conversion issues two setlocale calls.

>How-To-Repeat:

#include <locale.h>
int
main()
{
    for(;;) {
        setlocale(LC_ALL, "ru_RU.KOI8-R");
        setlocale(LC_ALL, "C");
    }
}

>Fix:
upgrade to current?
