Note, there was an additional fix to stabilize CI after this. I opened a GitHub PR with everything bundled together: https://github.com/ruby/ruby/pull/9841 ---------------------------------------- Bug #20209: YJIT can leak memory by retaining objects with singleton class https://bugs.ruby-lang.org/issues/20209#change-106604 * Author: alanwu (Alan Wu) * Status: Closed * Priority: Normal * Backport: 3.0: DONTNEED, 3.1: DONTNEED, 3.2: DONTNEED, 3.3: REQUIRED ---------------------------------------- We've received [reports](https://github.com/ruby/ruby/pull/9693) of YJIT causing memory leaks in production Rails apps by keeping objects that have singleton classes alive. The symptom is similar to #19436. We have found a workaround with https://github.com/ruby/ruby/pull/9693 and would like to have it in the next 3.3 point release. -- 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/postorius/lists/ruby-core.ml.ruby-lang.org/
