The crash only happens in debug builds. (`VM_CHECK_MODE > 0`) In release builds it can give the wrong line number in backtrace, if running in the interpreter, or when running in the JIT cause GC safety issues. -- 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/
