'Illegal Instruction' on L4Linux

Hello,


i have an issue with apps running on L4Linux.

/usr/bin # ./helloWorld
Illegal instruction

Actually, on the current l4re-snapshot-2015123115 my apps run without 
problem.
But, on l4re-snapshot-2014022818 or l4re-snapshot-2014092821 the same 
app don't works.
All apps say 'Illegal instruction'.

I've built for Zynq.


Any idea what's wrong?

(My project is stable on the old snapshots, that's why i try to avoid 
migrating to current snapshot.)



thanks,
