this python code made it crash

def hangup_hook(session, what, args=''):
       if what != "transfer":
               logerr("hangup hook for '%s' %s" % (what, session.cause()))
               return
       rawnr = session.getVariable("destination_number")
       caller = session.getVariable("caller_id_number")

removing the logerr line fixed the crash: it seems accessing "session" when what != "transfer" makes freeswitch crash!

to fix i guess freeswitch should set session=None when its not a transfer.
