This should not happen.  I would recommend recording a pcap file (with
wireshark) and looking at the exact OML message that has caused this problem.

A backtrace without the symbol names is not particularly useful.

can you actually provide a gdb backtrace from this?  As we don't have your
exact binaries for libosmocore + bsc_hack and your generated core file, we
cannot produce this ourselves.
