This is a fix related to #2145. While large PLY files load without crashing, if
cloud_->point_step * cloud_->width * cloud_->height
evaluates to something larger than4,294,967,295
it will overflow. This is easy to get if you have ~130,000,000 points and 11 fields which can result in a point step of 35, evaluating to4,550,000,000
(oops).Please let me know if you need an input to reproduce the problem / test the fix.
