The error occures if register is from r11 and higher ones is used. 
If register r10 is fixed the code uses r10 without initialisation whithin my
example.
To reduce the example is not possible I think because we need a called 
function which sould be called from not main and must use nearly all
registers.
So the send example is the shortest I have actually.
Maybe I can present a better one next days.
