Subject: [Xenomai-help] native skin 2.5.0: rt_task_create() segfaults if stacksize parameter too small

hi,

i have upgraded xenomai to 2.5.0 (x86,32bit). My application segfaults when I
try to create a task with stacksize 2048, this worked with 2.4.10.
Because my app is written in pascal i have reproduced the problem with the
xenomai trivial-periodic.c example:

-	rt_task_create(&demo_task, "trivial", 0, 99, 0);
+	rt_task_create(&demo_task, "trivial",16911, 99, 0);

Stacksize 0 -> default stack size : ok
Stacksize > 0 and <= 16911 : Segmentation fault
Stacksize >= 16912 : ok

Any hints ?

thank you
kisda
