Does the same bug exist in 3.7.1 or the CVS/development version?

This is from the manpage of TIFFSetField:

...
TIFFTAG_ROWSPERSTRIP            1      uint32             - must be > 0
...

So I can therefore only conclude that when I call this in my hacked tiffcp:

TIFFSetField(out, TIFFTAG_ROWSPERSTRIP, 8192);

and get:

antt@tux tools $ ./tiffdump testout.tif

testout.tif:

That this must be a bug. I would love to have my pitiful knowledge of c shown to be the problem!
