From: "esaron (Es Aron) via ruby-core" Date: 2025-11-05T22:28:27+00:00 Subject: [ruby-core:123696] [Ruby Bug#21670] 3.4.5 crashing with "try to mark T_NONE object" Issue #21670 has been updated by esaron (Es Aron). nrodriguez (Nicolas Rodriguez) wrote in #note-2: > @byroot https://bugs.ruby-lang.org/issues/21021 I don't know if #21021 is the same underlying issue. This instance occurs both with and without YJIT enabled on 3.4.5, and it looks like the fix for #21021 has been present since 3.4.2. I am optimistic that this may be one of the many write barrier issues fixed in 3.4.7 and we will be attempting to upgrade our Ruby version soon. ---------------------------------------- Bug #21670: 3.4.5 crashing with "try to mark T_NONE object" https://bugs.ruby-lang.org/issues/21670#change-115079 * Author: esaron (Es Aron) * Status: Open * ruby -v: ruby 3.4.5 (2025-07-16 revision 20cda200d3) +PRISM [x86_64-linux] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- We're experiencing a large number of crashes while running tests in CI on Ubuntu 22.04 runners. It is inconsistent, and we cannot reproduce reliably, although when the crash happens it appears to always happen in the same place, even if during different tests. This occurs both with and without YJIT enabled. ---Files-------------------------------- 3.4.5-crash-logs.txt (185 KB) -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/lists/ruby-core.ml.ruby-lang.org/
