The hooks of list->hooks can be xfreed during exec_hooks_body. That's because th->vm->trace_running is not incremented for exec_hooks_unprotected. So I fixed rb_threadptr_exec_event_hooks_orig to count exec_hooks_unprotected as th->vm->trace_running too. ---Files-------------------------------- ruby_2015-10-19-221406_P607.crash (18 KB) patch.diff (549 Bytes) -- https://bugs.ruby-lang.org/
