It is platform depended as to whether this works correctly. On x86-64 va_list is more complicated than a pointer to the stack because, for example, some arguments may be passed as registers.\n\nIn all instances where va_lists are reused, a va_copy should be performed instead.\n"},"comment":{"url":"https://api.github.com/repos/cadets/freebsd/issues/comments/267604113","html_url":"https://github.com/cadets/freebsd/issues/12#issuecomment-267604113","issue_url":"https://api.github.com/repos/cadets/freebsd/issues/12","id":267604113,"user":{"login":"gvnn3","id":2567712,"avatar_url":"https://avatars.githubusercontent.com/u/2567712?v=3","gravatar_id":"","url":"https://api.github.com/users/gvnn3","html_url":"https://github.com/gvnn3","followers_url":"https://api.github.com/users/gvnn3/followers","following_url":"https://api.github.com/users/gvnn3/following{/other_user}","gists_url":"https://api.github.com/users/gvnn3/gists{/gist_id}","starred_url":"https://api.github.com/users/gvnn3/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/gvnn3/subscriptions","organizations_url":"https://api.github.com/users/gvnn3/orgs","repos_url":"https://api.github.com/users/gvnn3/repos","events_url":"https://api.github.com/users/gvnn3/events{/privacy}","received_events_url":"https://api.github.com/users/gvnn3/received_events","type":"User","site_admin":false},"created_at":"2016-12-16T14:22:51Z","updated_at":"2016-12-16T14:22:51Z","body":"MFC'd on 28 Oct 2016\r\n\r\nhttps://svnweb.freebsd.org/changeset/base/308053"}}
