I'm having a similar problem, except that my problem doesn't seem to be caused by an update. I played a world I've had since 0.12 and it's worked fine. I played it on Wednesday. (Yes, 3 days before making this comment.) But since yesterday (on the day of the comment, it was yesterday) it's been crashing consistently on the same blocks when I go in any direction regardless of y-axis position (leading me to believe that's chunk boundaries). It doesn't crash on a world I made in 0.15.x or 0.14.x, though. I'm running on iOS 10.0.2 on an iPhone 6 with MCPE 0.15.10.
