I've looked into this a little more. Here's a slightly simpler test program:

  http://www.vips.ecs.soton.ac.uk/vips-7.11/repeat.c

It makes an n-page TIFF file by repeatedly copying a single tiled tiff. As soon as you go over 2GB, the output file becomes unreadable.

This is with standard ubuntu libtiff (3.8.2 at the moment I think). The problem is also present in tiff 4.0 alpha. It seems to affect 32-bit and 64-bit machines.
