I can confirm that the server does not crash when using charcoal.
It does, it crashed twice for me because of Charcoal. It crashes if the last burn tick does not have enough fuel left for a full burn tick. If it doesn't crash, it probably had exactly enough on the last burn tick.
Edit: To clarify, when you extinguish a fire a partial fuel item still exists, even though you don't see it. If you later on let the fire burn out, the last tick will try to burn a partial fuel item which causes a crash. It might also happen if for example an item of coal provides a different amount of fuel units (most crafting stations require 16 fuel units per tick) than the crafting station uses.
So to prevent crashes, extinguish your fires before they run out of fuel.
