Summary: setting locale randomly broken

This isnt 5.5 issue only, you can find it in any PHP version starting with 5.3.
localeconv() isnt thread safe and using it with _configthreadlocale() might lead
to unpredictable results. That's why bug #63688 was marked "won't fix" - a
solution, if any, might be very tricky.

Description:
------------
I am experiencing trouble setting the locale (with setlocale(LC_ALL, ...)) in my
code. With PHP 5.4, it always worked as expected, with 5.5 it appears that the
locale has been changed, but localeconv() is still returning old values and
functions like printf('%f') do not behave as expected.
I have disabled the new Opcache, but the random behaviour persisted. I can't tell
when it happens and why it sometimes doesn't work. It seems (to me) that there is
some kind of threading problem, as I can have the same code in different browser
tabs and get different results.
I am using PHP 5.5.0 VC11 TS x86 on Windows 7 x64, loaded as a module into my
Apache 2.4.3, which is running as a service.
Test script:
---------------
<?php
function test($locale, $value) {
$newlocale = setlocale(LC_ALL, $locale);
$conv = localeconv();
$sep = $conv['decimal_point'];
printf("%s\n--------------------------\n", $newlocale);
printf(" sep: %s\n", $sep);
printf(" %%f: %f\n", $value);
printf(" %%F: %F\n", $value);
printf("date: %s\n", strftime('%x'));
printf("\n");
}
test('german', 3.41);
test('english', 3.41);
test('french', 3.41);
test('german', 3.41);
Expected result:
----------------
German_Germany.1252
