Description:
------------
When PHP uses only 1 thread, i.e. CGI or CLI, it should produce exactly the same output, right?

But after days of trouble shooting I finally find the issue with PrestaShop installer. The issue is PHP on Windows.

When you download the latest version of PrestaShop https://github.com/PrestaShop/PrestaShop/releases/download/1.7.6.2/prestashop_1.7.6.2.zip , unzip it and
a) install it from CLI using admin/install_cli.php
b) OR install thru web using PHP CGI

the install always fail with NTS PHP (with error Template "C:\wamp64\www\ps\mails\themes\modern\core\account.html.twig" is not defined.), but always succeed when run with TS PHP.

I tested it on multiple Windows systems and two versions of PHP - 7.3.9 and 7.3.12/latest. The install always completes with the TS version of PHP, but always fail with the NTS one.

I am posting it here and not in the PrestaShop repo, as this seems like some core PHP issue.

Can you please reproduce and fix?

Test script:
---------------
see description

Expected result:
----------------
no difference between TS and NTS version, i.e. the PrestaShop installed always succeed

Actual result:
--------------
TS build is working correctly, but the NTS build of the same PHP version (and config, file location, ...) does something unclear differently
