Subject: [Xenomai-help] Strange SIGXCPU signal at rt_task_trampoline
Date: Fri, 24 Nov 2006 14:48:19 +0100 (CET) [thread overview]
Message-ID: <29451992.1164376099993.JavaMail.ngmail@domain.hid> (raw)
Hi all,
I have the strange effect, that I get a reproducable SIGXCPU signal in gdb
when running my Xenomai (native skin) application.
It occurs in rt_task_trampoline() within the do..while loop.
The situation is that I am re-creating and starting a task that has been
terminated before.
Unfortunately I was not able to create a very simple application that shows this
effect.
I am using xenomai (SVN 1882), Pentium 4, gcc 4.1.2
I have enclosed the output of the gdb session:
