From: "jeremyevans0 (Jeremy Evans)" Date: 2021-11-16T21:07:21+00:00 Subject: [ruby-core:106101] [Ruby master Bug#18343] empty hash passed to Array#pack causes Segmentation fault (2.6) Issue #18343 has been updated by jeremyevans0 (Jeremy Evans). Backport changed from 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN to 2.6: REQUIRED, 2.7: DONTNEED, 3.0: DONTNEED Status changed from Open to Closed This is definitely a bug in ruby 2.4 - 2.6, but ruby 2.4 and 2.5 are end of life, and ruby 2.6 is in security maintenance mode. I don't think this is a security issue, but just in case, I'll mark this for backporting for ruby 2.6. It is up to the ruby 2.6 branch maintainer whether it is actually backported. ---------------------------------------- Bug #18343: empty hash passed to Array#pack causes Segmentation fault (2.6) https://bugs.ruby-lang.org/issues/18343#change-94690 * Author: Ethan (Ethan -) * Status: Closed * Priority: Normal * ruby -v: ruby 2.6.8p205 (2021-07-07 revision 67951) [x86_64-linux] * Backport: 2.6: REQUIRED, 2.7: DONTNEED, 3.0: DONTNEED ---------------------------------------- passing an empty hash to `Array#pack` segfaults from ruby 2.4 to ruby 2.6 on ubuntu, macos, and windows. ```ruby [0].pack('c', {}) ``` pack takes a keyword argument, and handles unknown keywords, but the empty hash segfaults. here is the error trace in a github workflow running only the above expression: https://github.com/notEthan/jsi/runs/4226433638 (other ruby versions and OSes are part of the same run) -- https://bugs.ruby-lang.org/ Unsubscribe:
