| State-Changed-Why:
| This is runtime problem that missaligns stack frame of function main. You need to update to runtime compiled with gcc 3.0+ or not use aligned data in the function main (gcc aligns outgoing frame so the called functions will be aligned properly)
Jan,
Please could you add a note to that effect in the documentation?
Thanks,
