Hi,
in response to my last email to the list, I got into contact with steve-m via another means of communication.
For future reference: osmocom-bb on the DP-L10 phone needs this patch to be successfully compiled on GCC newer then 4.8:
http://git.osmocom.org/osmocom-bb/commit/?id=a903b3c1ee27047c79728b18ff6340d...
The jolly/testing branch doesn't contain that fix. It can be added/hacked in via "git cherry-pick a903b3c1ee27047c79728b18ff6340d23d1aad2e"
Many thanks to steve-m for pointing me to this patch in his first response email and absolutly nailing the bug :)
So long, Tobias
