[Xenomai] Assertion current-magic 0 failed

["Stéphane Reichert" <sreichert@sepro-group.com>]

Hi,

I am testing the new version 3.0.7 on our system (iMX 6 on 4.1.46 kernel), 
and I would like to know
if anybody else encountered this error :

threadobj.c:1344: threadobj_prologue: Assertion `current->magic == 0' 
failed.

I compile the kernel with --enable-pshared --enable 
registry --enable-debug=full.

Here is a backtrace I get on the debug signal callback:

# Mode switch (reason: triggered fault), aborting. Backtrace:
