Re: [Xenomai] Re : Sporadic problem : rt_task_sleep locked after debugging

[Paolo Minazzi <Paolo.Minazzi@mitrol.it>]

Hi Gilles,
I have added a check in

file          :   xenomai-2.5.6/ksrc/skins/native/task.c
function      :   int rt_task_delete(RT_TASK *task)

See my code signed with =======>

It seems if I'm working with a gdb session, the rt_task_delete() keep 
the lock of the killed thread.
With my additional check, all seems ok.

I could also insert my check directly in xnpod_delete_thread().

What do you think about ?
Paolo
