 I test it in 32bit machine. I wonder if you compile in 32bit mode and it seems
that it only crashes in 32 bit .

Proposed patch

Hi Skysider,

  Unfortunately I could not reproduce the failure that you reported,
  but I do agree that integer overflow could occur at that point in
  the code.  So please could you try out this patch and let me know
  if it solves the problem for you.

Cheers
  Nick
