Sam,

   We, as I am sure with many others, have been using the TIFF library
for years.  A while ago, I installed ver3.4beta035, compiled it on a
SPARC20 running Solaris 2.4 with SUNPRO C4.0 compiler.  For the most
part everything works. The image always comes through. But for every
line that is read I get the message:

 LZWDecode: Bogus encoding, loop in the code table; scanline xxx
     .
     .
     .


If I write the file with rowsperstrip equal to 1, no problem.  Anything
else is a problem.  I have tried it on SunOS and get the same thing. 
Rather that use my api's into the library I used the tiffcp utility and
get the same problem.  Any idea why?
