Thanks for reporting it, I will have a look at it this weekend.

Please make these changes to the workflow as a workaround for now and that should fix it.

• Change mcrypt to mcrypt-1.0.7 for PHP 8.4.
• Specify MCRYPT_LIBS: libmcrypt-dev as env to the setup-php step.

Is it a temporary glitch?

I saw it failing also in https://github.com/SAML-Toolkits/php-saml/actions/runs/11746411244/job/32747989690?pr=600

but I see it working in https://github.com/nextcloud/server/actions/runs/11746255419/job/32725600041?pr=49164

Interesting, I've just started seeing this in one repo too:

PHP Warning:  PHP Startup: Unable to load dynamic library 'mbstring.so' (tried: /usr/lib/php/20240924/mbstring.so (/usr/lib/php/20240924/mbstring.so: undefined symbol: php_pcre2_code_free), /usr/lib/php/20240924/mbstring.so.so (/usr/lib/php/20240924/mbstring.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

However, as PHPUnit requires MBString, I know that if no extensions are explicitly passed, it works just fine (as otherwise I would have seen failing builds on PHP 8.4 on dozens of other repos too).

So, it feels like this is only an issue if with: extensions: mbstring is explicitly passed.
