unit with 2 planned moves.
Project: Battle for Wesnoth

_______________________________________________________
Details:
This only happen when the first move is executed. If the two moves are
executed at the same time (with an execute_all), there is no problem.
This make the whiteboard unusable for multi-turn moves.
Only the allies segfault, not the client executing the move.

this is NULL in unit::underlying_id since move->get_unit() returns NULL.
