Sorry, but I have to ask again:
Can you tell me what is the right thing to do now?

Is there a newer version than the one included with my ucLinux-dist 
(uClibc 0.9.27) where this bug is solved?
I think there is 0.9.28! How can i find out if the bug is fixed? 
Or is there a workaround for the problem?

Thanks for your help!
