PHP 8.3: Warning about passing argument 1 of 'zval_ptr_dtor' from incompatible pointer type

Here is what the compilation says:

/opt/php/src/ext/yaml/parse.c: In function 'handle_sequence':

That warning was fixed by https://github.com/php/pecl-file_formats-yaml/pull/74 (https://github.com/php/pecl-file_formats-yaml/commit/e7bffc01c496ef36ce672c612984b13a27426788). This and a few other small fixes have not yet been released but are available from the php7 default branch.

Thanks! I would not have checked the php7 branch for this… 🙈 Great to hear – and "small fixes" sounds like nothing that would block a release around the time PHP 8.3 is released as stable. 🎉

When would such a release be available? We have php 8.3 out for a long time now.

Folks, I have a problem... I'd like to install php yaml extension on Fedora 40 using pecl (php-pecl-yaml rpm package is no longer available on F40), but...

# pecl install yaml
