Subject: [ruby-dev:47637] [ruby-trunk - Bug #5808] "a = []; a << a; puts JSON.dump(a)" aborted
Date: Mon, 19 Aug 2013 11:45:27 +0900 [thread overview]
Message-ID: <redmine.journal-41268.20130819114527@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-5808.20111226124532@ruby-lang.org
Issue #5808 has been updated by knu (Akinori MUSHA).
Oj and Yajl have no cycle detection or depth limit either.
Maybe it's worth contacting authors of all known JSON libraries, probably via the multi_json project.
