Ufff, I think I've found the problem. If libc is compiled with gcc41
it does not work. If I compile it with gcc34 it works fine.
The snapshots on chlamydia are compiled with gcc34, that's why it 
worked there.
Can someone please confirm that it does not work with a gcc41-compiled
libc?
Note, that you need to fix the typo spotted by Joerg!
