Bug description:strftime format %Z crash php

Description:
------------
Since Windows 10 1803 php crash the apache service (httpd.exe),
when setlocal is called in the "wrong" order and then strftime is called
with %Z format on all other formats like %z the "crash" doesn't happen.

Wrong order:
setlocale(LC_TIME,'en_US.UTF-8');
setlocale(LC_CTYPE,'en_US.UTF-8');
strftime('%Z');

Right order:
setlocale(LC_CTYPE,'en_US.UTF-8');
setlocale(LC_TIME,'en_US.UTF-8');
strftime('%Z');

Error is notice in alle php 7+ version (5.6 doesn't had this issue)
tested version:  5.6.35 (no issue here) ,7.0.29, 7.1.16, 7.2.4, 7.2.5

Test script:
---------------
<?php
$value = strftime('%Z');
echo $value.'%Z';
echo '<br>';

setlocale(LC_TIME,'en_US.UTF-8');
$value = strftime('%Z');
echo $value.'%Z';
echo '<br>';

setlocale(LC_CTYPE,'en_US.UTF-8');
// here came the crash in the next line
$value = strftime('%Z');
echo $value.'%Z';
echo '<br>';

Expected result:
----------------
Result should be that it behavior in the same as when you run %z.
