Not only the failing tests, but also LeakChecker is reacting to MJIT compiler processes and it can also solve the problem. An orphan process that continuously spawns compiler processes could be seen as a harmful process for people unfamiliar with MJIT, but we would be able to rename the process to indicate it's Ruby's JIT compiler. I'm not sure if the invoker process can be properly killed when the main Ruby process exits abnormally and fails to call a finalizer that usually kills the invoker process on Ruby's exit. ---------------------------------------- Bug #14867: Process.wait can wait for MJIT compiler process https://bugs.ruby-lang.org/issues/14867#change-72626 * Author: k0kubun (Takashi Kokubun) * Status: Open * Priority: Normal * Assignee: k0kubun (Takashi Kokubun) * Target version: * ruby -v: * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- If Ruby tries to wait for any child process, MJIT's gcc/clang process could be caught by the method call. It's not convenient for both Ruby's user and MJIT worker thread, so Process.wait and its families should somehow avoid waiting for it. -- https://bugs.ruby-lang.org/ Unsubscribe:
