The most common problem is with code which assumes that a returned file offset or size can be stored in a 32-bit type.

Are there tag values that have been changed from 32-bit to 64-bit? Does it still work if we call something like:

     TIFFSetField(myTiff, TIFFTAG_ROWSPERSTRIP, rowsperstrip);

where rowsperstrip is a 32-bit integer?

TIFFTAG_ROWSPERSTRIP is still limited to 32-bits. However, tags which return file offsets or object sizes are necessarily 64-bits. These tags are 64-bits:

   TIFFTAG_STRIPOFFSETS
   TIFFTAG_STRIPBYTECOUNTS
   TIFFTAG_FREEOFFSETS
   TIFFTAG_FREEBYTECOUNTS
   TIFFTAG_TILEOFFSETS
   TIFFTAG_TILEBYTECOUNTS
