### Description
The following code:
```php
<?php
var_dump(mb_strimwidth("あいうえお", 1, 3));'
```
Resulted in this output:
```
Segmentation fault
```
But I expected this output instead:
```
string(3) "い"
```
PHP <= 8.1 works fine. Reproduced PHP 8.2 beta2 only
### PHP Version
PHP 8.2.0 beta2
### Operating System
Ubuntu 20.04 on WSL2
