Yes, I know. But all this is working fine. Using -Os had solved the
problem.

Without the Makefile is would be a snippet. ;-)
For now I have the problem, that I can't reproduce the code which leads
to the missing code. I've worked on the project after posting here. The
code snippet I had extracted this morning doesn't show the problem too.
So I have to play with it in order to get the same effects.
I've talked to an colleague this morning. He had the same problems with
WinAVR a few months ago. His solution was adding a asm volatile("nop")
between cbi() and sbi(). He had to generate a bus timing by software.
At the end, I don't have a snippet. But I'm trying to reproduce the effect.
