I'm having a problem on my first call to TIFFReadScanLine() with second and third parameters set to 0.

The error is occurring in TIFFSeek() at line 339 of tifread.c as row is zero and td->td_image length is also zero :(

I've made no changes to my client code for 4.1.0 - do I need to?

It seems like you should provide us with more obvious details such as:

• If you built libtiff yourself or you are using a libtiff built by someone else.
• The operating system and compiler you are using.
• The output from 'tiffinfo' for the TIFF file you are testing with.
• If using Microsoft Windows, which I/O implementation was selected.
• If the program is a 32 or 64-bit application.
