Yes. I guess PTRACE_ATTACH should work but it is pointless, this
thread can't report an event and other ptrace requests won't work.
In fact I think PTRACE_ATTACH should fail in this case...
I have used PTRACE_SEIZE instead:
ptrace(PTRACE_SEIZE, 13902, 0, 0) = 0
ptrace(PTRACE_INTERRUPT, 13902, 0, 0) = 0
- here close(0);
wait4(13902, [{WIFSIGNALED(s) && WTERMSIG(s) == SIGSEGV && WCOREDUMP(s)}],
__WALL, NULL) = 13902
