There is a fix for the SIGSEGV issue checked into a branch that you
might be able to try. I can positively confirm that the issue is fixed
on my scanner and I can scan properly. This was a proper bug that was
revealed by the 64-bit side of things.

I will not close the issue or merge the branch just yet. I noticed that
there is the odd stall in USB reading which means that I have to power
cycle the scanner to get around. I will try to figure out what is going
on there. It is probably unrelated to the issue above though.

Cheers,
Ralph
