Thanks for your reply.

Please not that it works fine for the standalone application.

Just in case, the task is created inside a staticaly linked shared 
object the error occurs.

Here ist the config:

CONFIG_MMU=1
CONFIG_SMP=1
CONFIG_XENO_BUILD_ARGS=" '--prefix=/usr' 
'--includedir=/usr/include/xenomai' '--mandir=/usr/share/man' 
'--with-testdir=/usr/lib/xenomai/testsuite' '--build' 'x86_64-linux-gnu'
