Unallocated memory or corrupt memory access while drawing Passable areas #254

Description

@xezon

Original game source: game disc

  • Reproducible in the original Generals Zero Hour?
    Multiplayer affected?
    Are you using any mods? (like Gentool, Rise of the Reds or Contra)

Issue explanation

The game is either accessing memory it hasn't allocated or something is corrupting it resulting in this when the debug bool for drawing passable areas is enabled, most of the time enabling the bool seemingly cause of this bug causes the game to crash. On rare occasions it does work.

    How is this enabled? i wouldn't mind checking this since i am investigating various pathfinding issues.
    In debug builds we have the ctrl + a hotkey to cycle through various debug overlays for pathfinding but i have not seen the above.
