Just to report back the fix below solved my problem. Reprocessed all the
imagery and no errors reported, and no nasty artifacts on the images.
Many thank to Even for his copious help and to the whole GDAL team.

It belatedly dawned on me that just rebuilding the gdal package to use
the internal libtiff would be MUCH easier the messing around with the
libtiff packages.
In case anyone else needs to do this on debian:
cd /usr/src
apt-src install libgdal1-1.5.0
cd gdal-1.5.2
vi debian/rules

Steve,
yes you're looking at the correct site. None of those versions have been
released yet. But they are both in a state close to being released.
For the test, I didn't use the .tar.gz but the CVS version.
To get libtiff 3.9 CVS head (Extract from

Even,
Thank you for all the extra work you did, I very much appreciate it.
Looks like I get to spend my weekend trying to rebuild the Lenny Source
package for libtiff based on 3.9.0.
This is probably not the right list, but looking at:

3.9.0 looks to
Stephen,
I've managed to reproduce your issue with GDAL 1.5 compiled with libtiff 3.8.2
(and I'm not so surprised, as I remember that it was a known issue). But when
built with internal libtiff or against external libtiff 3.9.0 (CVS head
version), it works fine. So it is due to some bug in libt
So is the conclusion on this issue, that Debian has old/bad? libtiff
libraries? What version libtiff do I need to make this work correctly?
Is gdal 1.5.2 a reasonable version to be running under? I would like to
stay under the package management system as much as possible.
But I also need to
Even,
I ran gdalinfo -checksum on all 51GB of images and none of them reported
any errors. And none of the images are compressed.
I'm using Debian Lenny packages. There is an ldd output below.

Hi,
no those warnings don't sound good at all ! The number of overviews should be
fine too.
Could you precise the version of GDAL you're using and if you have built with
internal libtiff or external libtiff ?
(Such warnings could happen with older libtiff, especially with TIFF
compression)
