I isolated the failure to the recent zlib update and then found someone else from the Arch forum had also found a [zlib problem in an SDL game](https://bbs.archlinux.org/viewtopic.php?id=222116).\r\n\r\n\r\n\r\n@michelboaventura had also seen the `dialyzer` issue using 1.2.11 on gentoo, after hearing it was linked to zlib  he was kind enough to bisect the zlib commit history and isolated the fault to b516b4bdd7c0c9f0858adfebf732089014f7b282 (this is reported in this [thread](http://erlang.org/pipermail/erlang-bugs/2017-January/005206.html)). The same commit was confirmed to be where the issue was introduced in the manaplus game mentioned in the Arch thread.\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/madler/zlib/issues/comments/274950307","html_url":"https://github.com/madler/zlib/issues/206#issuecomment-274950307","issue_url":"https://api.github.com/repos/madler/zlib/issues/206","id":274950307,"user":{"login":"4144","id":959758,"avatar_url":"https://avatars.githubusercontent.com/u/959758?v=3","gravatar_id":"","url":"https://api.github.com/users/4144","html_url":"https://github.com/4144","followers_url":"https://api.github.com/users/4144/followers","following_url":"https://api.github.com/users/4144/following{/other_user}","gists_url":"https://api.github.com/users/4144/gists{/gist_id}","starred_url":"https://api.github.com/users/4144/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/4144/subscriptions","organizations_url":"https://api.github.com/users/4144/orgs","repos_url":"https://api.github.com/users/4144/repos","events_url":"https://api.github.com/users/4144/events{/privacy}","received_events_url":"https://api.github.com/users/4144/received_events","type":"User","site_admin":false},"created_at":"2017-01-24T21:51:06Z","updated_at":"2017-01-24T21:51:06Z","body":"I think it's ok only with replacing memcpy to inflateCopy.
