but we have not hit this case yet (e.g. no re-establishment occured right now). Do you have an idea of why this doesn't crash right now?
this is because openbsc does not do re-establishment in case of a data link failure. osmocombb uses resume for assignment (which causes the same function as re-establishment), but for this case, lapdm.c will provide a zero-length msg.
