I missed this on initial reading.  Thanks for pointing it out and
letting me learn some more.

GDAL 1.7.3 in OSGeo4W only crashes on this collection of geotiffs and
works fine on other files.  Thanks for spending time on what is
probably perceived by you as an ancient version and probably of little
interest to you.  You are always making the future better; thanks for
all your work in that regard.  Thanks also for going out of your way
to help all users at all levels.  I've found the GDAL-dev list to be
kind and welcoming to all who write.

Sincerely, Eli
