Hi Holger,
I was able to narrow it down, and it seems this is the patch that
causing the problem:
http://cgit.osmocom.org/libosmocore/commit/?id=f5a079f739c57d8be7c59149fd45…
Up to that patch it works (more or less), but after I applied it, I
got this seg faults.
I don't know how to do back traces but I try to get some info about
this topic and will send the results.
