Registry settings are no longer recognized

Description

Since PHP 8.1 local settings of a workdir (from registry of windows) are loaded for scripts from another directory (Case D in STR).
Is it bug or new feature of PHP 8.1?

STR:

• Create directory like C:/Inetpub/vhost/mydomain.tld/httpdocs
• Create index.php with phpinfo() in the directory
• Set local config "open_basedir=test" for the directory by registry of windows
• Create index.php with phpinfo() in another location

Case A (PHP 8.0.14):

cd C:/Inetpub/vhost/mydomain.tld/httpdocs
php -f index.php | grep open_basedir

Actual result: open_basedir = test

Case B (PHP 8.0.14):

cd C:/Inetpub/vhost/mydomain.tld/httpdocs
php -f /another/index.php | grep open_basedir

Actual result: open_basedir = null

Case C (PHP 8.1.4):

cd C:/Inetpub/vhost/mydomain.tld/httpdocs
php -f index.php | grep open_basedir

Actual result: open_basedir = test

Case D (PHP 8.1.4):

cd C:/Inetpub/vhost/mydomain.tld/httpdocs
php -f /another/index.php | grep open_basedir

Actual result: open_basedir = test, but expected NULL (like php 8.0)

Sounds like you found an explanation and it wasn't PHP?

I had doubts so I decided to double check
I added the screenshot of real test

What if you run outside of Cygwin? What if you don't run any PHP file but output settings using the -i flag? And

local settings of a workdir (from registry of windows)

exactly what do you mean by that?

I repeated all cases via CMD of Windows - same result.

open_basedir = no-value

exactly what do you mean by that?

I don't see anything in the changelog that says something was fixed in PHP 8.1.

Me too, but behavior of PHP is changed on 8.1, I think

This is a pretty serious bug, introduced when the Zend Stream API has been changed to use zend_string* instead of char*, but it apparently has been overlooked to fix the calls to UpdateIniFromRegistry() which still expects a char*. Since there was a cast, the compiler didn't warn about that misuse.

Which versions are affected? 8.1.0-8.1.4?
