Exit code: 2

But I expected this output instead:

Build with the current GCC version should succeed.

@ryandesign FYI

PHP Version

PHP 8.4.0beta3

Operating System

macOS 10.6

Commencez par main/streams/cast.c à la ligne 142 et reproduisez le build de PHP 8.4.0beta3 avec GCC 14 sur macOS 10.6. Comparez le type du callback du seeker avec la déclaration de la fonction de cookie du stream. C’est terminé lorsque le build s’achève sans l’erreur incompatible-pointer-types ; la pull request liée 15702 indique que le travail est déjà en cours.
