Tracked in Fedora Rawhide at https://bugzilla.redhat.com/show_bug.cgi?id=2261817.

@sagitter Thanks for the report, I'll check it when I'll time (currently I have few)
Lecrapouille commented
@noloader oooh I was not aware that this lib or the initial author's lib was used in Fedora! I'm using Debian I'm stucked with gcc-10
Lecrapouille commented
As said in #9 I cannot accept to use the minzip version referred by @nolaoder because mine is fresher (AES) the issue is in the ioapi_buf.c that was not present in the referred version. I'll try to get a newer gcc version.
Lecrapouille commented
I have updated my Debian to version 12. I have g++-12 and also the warnings. I'll try to fix them
