It is strange, I will check with my installation.<br>
Now you can try to use more older version of libosmocore.<br>
Just checkout your libosmocore:<br>
git checkout a652abc5bf75435ba7f1c96ed914cf5805fc326f<br>
After that recompile and reinstall libosmocore, libosmo-abis, openbsc<br>
and osmo-bts.<br>
