Battle: FPE in Mystic Sunrise (2k3 1.10 sample game)

[fdelapena]

This game uses gauge style battle. It seems like something is wrong in some gauge drawing.

Game download.

Not tested if the 2k3 1.10 RPG_RT executable is a custom one for this particular game (it shouldn't as "sample game" but...).

Just try to launch some game battle, e.g. new game, select skip scene and leave the room.

Or just launch any battle, e.g. --battle-test 4 (4 is the battle group ID when leaving the room).

GDB backtrace:
