Bug: Potential crash in compass code with somewhere exits
Danger: High - Potential game crash.
Discovered in: AFKMud 2.0
Found by: Kayle
Fixed by: Kayle

---

act_info.c, print_compass

Locate:
   int exit_info[] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };


Change to:
   int exit_info[] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };


A subtle yet deadly problem. Players who turn on the compass display code have the potential for crashing the game if they walk into a room with a somewhere exit. The reason for this was that the exit_info array was missing a value. In C/C++ arrays begin counting from 0, not 1, so it needed another 0 to account for exits having values ranging from 0 to 10.
