Exit code: 2
But I expected this output instead:
Build with the current GCC version should succeed.

Research direction
Start with main/streams/cast.c at line 142 and reproduce the PHP 8.4.0beta3 build using GCC 14 on macOS 10.6. Compare the seeker callback type with the stream cookie function declaration. Done means the build completes without the incompatible-pointer-types error; linked pull request 15702 indicates work is already underway.
