Good obervation Erik, although I get the same result with heightOfRow set to 500 and 1, the critical point is still 63632 rows.

I have not verified it, but doing the math in my head, 63632 * 160 seems just large enough that it can not be completely represented in a 32 floating point type. At a minimum, I would expect display glitches when you create a table view that is more than 10 million Postscript points tall. That would after all only require 14 thousand pages to print on 8.5x11 inch paper assuming 10 useful inches per page...

Anyway, perhaps some dangerous casting is going on somewhere (possibly even in the frameworks), and a table that tall results in an address calculation with a negative offset or something else unsafe.
