the problem is that I can not remove the -O, because the code gets 
too big then. I have to use at least -O1.

I do not know if it is really the optimization - it was sometimes 
difficult to find the exact location and such with IAR-compiled code, 
but it worked - now I end up in the completely wrong function (some 
100 lines away), so I assume it is not only optimization but a 
somewhat more basic problem.

Is there anything special concerning preprocessing etc. I might have 
a look at?
