Bug #81693 mb_check_encoding does not return a value but quits php
Submitted: 2021-12-03 14:27 UTC Modified: 2021-12-04 10:45 UTC
From: richardbrinkman at hotmail dot com Assigned: cmb (profile)
Status: Closed Package: mbstring related
PHP Version: 8.1.0 OS: Debian (php:8.1-apache docker)
Private report: No CVE-ID: None

Description:
------------
Write a file test.php with the content of the attached test script:

Run this script with "php test.php" results in: 
Segmentation fault (core dumped)

I use the php:apache Docker image.

If I run the same script with the php:8.0-apache Docker image then it will return the correct:
bool(true)

Both docker images install mbstring with:
docker-php-ext-install mbstring



Test script:
---------------
<?php
    var_dump(mb_check_encoding('Hello world', '7bit'));
?>


Expected result:
----------------
bool(true)

Actual result:
--------------
Segmentation fault (core dumped)
