I also get a crash with that error code, though in my case it's in the Chapter 11 victory scene. I did not, unfortunately, save during the fight, so reproducing it is going to have to wait a bit as that battle is ridiculously luck-dependent (your continual refusal to give hitpoints on levelups means that the entire party is made of paper and dies very easily, which is a bit of an issue when outnumbered 10 to 1).
