Gran Turismo crashses with bus error

[batman52]

It looks like every time i play a single race in arcade mode, it crashes randomly in time with a bus error. Default graphic configuration, but frameskip 2/3. schp7502.bin.

EDIT: it happens even with frameskipping 0/1

maybe it's about this?

This has nothing to do with alignment. (The very point of catching unaligned accesses in the kernel is so it will NOT crash.)

Probably an issue with the tracing of constant addresses for doing direct loads/stores without the use of helper functions.
