Steve,

I imagine the problem is due to a broken system libtiff.  You
can check the integrity of the original file using:

  gdalinfo -checksum file1.tif

I would suggest trying to rebuild GDAL using the internal libtiff.  The
system libtiff often has subtle issues with overview building which
requires zipping back and forth between the base and overview
image when doing io.

Best regards,
