Hi Igor, sorry for delay... On 04/12, Igor Zhbanov wrote: > > Hi Oleg, > > So what is the cause of this problem? The cause is clear. And well known ;) And again, this has almost nothing to do with the mutual debugging. The tracee sleeps in ptrace_stop(). You send SIGKILL. This wakes the tracee up, it dequeues the signal, calls do_exit(), and stops again in PTRACE_EVENT_EXIT. With SIGKILL in signal->shared_pending. This all looks as if the tracee doesn't react to SIGKILL. The only problem is that any change can break something which relies on the current behaviour :/ I'll write another email on this. Oleg.
