You can crash the game by using the "Shift-A" hotkey and giving an order that some selected items can't perform. The description for "Shift-A" is "Select All Ships in Ship List" but it really selects all of your things in the selected sector (planets, ships, bases, sats, mines, etc).

So, for instance, if you have a sector with a planet, ships, sats and mines in it, and you Shift-A and then click on an individual ship and hit hit "Y" for "Sentry", you will get a range check error. This can also happen if you "Shift-Click" units that can't receive whatever order you give them.
