Accessing unit->iseq->body outside of critical section seems wrong and I hit a segfault: Thanks to report, I'll take a look at that once I go home. ---------------------------------------- Bug #14867: Process.wait can wait for MJIT compiler process https://bugs.ruby-lang.org/issues/14867#change-74670 * Author: k0kubun (Takashi Kokubun) * Status: Assigned * Priority: Normal * Assignee: normalperson (Eric Wong) * 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. ---Files-------------------------------- 0001-hijack-SIGCHLD-handler-for-internal-use.patch (13.8 KB) JIT-test-all.log (39.9 KB) mjit_test-all_63796.log (40.4 KB) config_ruby-loco_mingw.log (27 KB) test_jit_results.txt (41.2 KB) 14867_91_mingw_build_log_.txt (127 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
