Thks for your anwsering.> Note that there’s no objc_sync_enter in the backtrace, indicating that @synchronized is not involved.LizhiFM app use @synchronized to serially run SQLite, however, no objc_sync_enter in the backtrace, it's very strange. i guess there might be a system action to stop @synchronized lock and send SIGTRAP.
