I didn't see any mention of this in https://github.com/madler/zlib so I filed https://github.com/madler/zlib/issues/1142 . Note once again, this is in a utility in the contrib directory, not the main zlib library itself. (And 1.3.1.2 is not an actual release, but a git tag being used for other purposes - see https://github.com/madler/zlib/discussions/1128 .)
The bug has been closed now that untgz has been removed from the zlib contrib directory so that people stop harassing the zlib maintainers about code they don't maintain: https://github.com/madler/zlib/commit/1a40058a92d525aa49a6eac698cfde500fc9b92f -- -Alan Coopersmith- alan.coopersmith () oracle com Oracle Solaris Engineering - https://blogs.oracle.com/solaris
