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

Bắt đầu với main/streams/cast.c tại dòng 142 và tái hiện bản build PHP 8.4.0beta3 bằng GCC 14 trên macOS 10.6. So sánh kiểu của seeker callback với khai báo hàm stream cookie. Được xem là hoàn tất khi bản build hoàn thành mà không có lỗi incompatible-pointer-types; pull request 15702 được liên kết cho thấy công việc đã được tiến hành.
