0.22.0: zlib(finalizer): the stream was freed prematurely

[zhulik]

Hello,

after updating to 0.22.0 from 0.19.2 and making adjustments for the new read/write interface I started getting warnings from zlib:

zlib(finalizer): the stream was freed prematurely.

Besides that my code works as expected.

I couldn't precisely trace what exactly causes printing of this warning, do you have any ideas where I can start from?

Thanks!

Some updates: warning is only shown with ruby 2.7 and 3.0, 3.1 is not affected. This PR in zlib simply disables warnings ruby/zlib#30. I assume we can't do anything but updating ruby to 3.1

Yeah I removed that message from the CRuby native extension for zlib. Thanks for confirming the fix!
