Luke: this same bug was present in 3.2, it's because opermode is not set to 0 after calling do_mode in m_mode/m_samode, so it will stay at 1 or 2... then in the next sjoin call which calls set_mode directly it will think it needs to send a operoverride message (which it shouldn't) and crashes because of a NULL pointer. |
