The main issue here is, that ais has found only 2 cp, but there are 6 parameters to optimize. Then the optimizer goes haywire and the autocrop hangs.
I added an additional check to prevent this loop.

Title:
  align_image_stack hangs

Status in Hugin:
  Fix Committed

Bug description:
  I have an application that uses align_image_stack, which works very well.
  Unfortunately it sometimes hangs up when aligning two images, I assume that's because they are too difficult to align. It states "Number of good matches: 0, bad matches: 40" many times, then that it has done "n iterations" up to 259. At that point it states "Run called" and then gets stuck. This would be alright if I was using it from a terminal, but it's embarrassing when it does it in my app - there's no easy way to detect the condition and stop it.
  It would be better to prevent it - is that possible? If not I think it's a bug. I can supply the two  images.
