[madebr]

When crashing against a palm tree with a smoking (=broken) car in Mayan Mayhem (first map of Carmageddon Splat Pack), the game segfaults.

The following stack trace is print:

How to reproduce

• Start DethRace with DETHRACE_ROOT_DIR pointing to a splat pack directory
• Start a new game, select Max Damage, any difficulty, and start the Mayan Mayhem race
• When in-race, Enter IBETYOUCANTPRINTCUNT for entering the edit mode
• Press F4 until you enter "damage edit mode"
• Make speed (but not too much to not trigger #131), drive a bit around in the grass and crash against a palm tree. Before you crash, make sure you have a damaged car that generates smoke. Use the the keys 0-6 (combined with SHIFT) for that.
