I can confirm that the camera do not crash at ISO 400 or lower, but crashes if you shoot at a ISO above 400.
I also experience crashes while shooting video (1080p) but this may also have to do with the above bug as it seems to occur more often in low light than in high light situations. (i don't think it is possible to se which ISO is being used while recording video).
I have tested manual flash, which is working.

I do not quite understand what you mean by "where abouts are they found in the CHDK menus; which this bug is happening?"
But if you mean where you can find the option to set aperture, it is in Extra Photo Operations --> Override aperture
Thanks for your big work with porting this
