mapserv segfaults

[John C Cartwright]

Hi Sean,

Don't really know why it's picking up the libtiff from the ArcSDE
directory, but after various permutations of reording the
LD_LIBRARY_PATH, recompiling GDAL and Mapserver, and even linking the
libtiff in ArcSDE to the one in /usr/lib, I finally gave up and removed
SDE support from the mapserver compilation. Then recompiled GDAL,
Mapserver. Now recieve a similar error, but using the /usr/lib/libtiff.

Any ideas on what I should try next? I specified
--with-libtiff=internal --with-geotiff=internal in the GDAL config.  If
I specify a --with-tiff=DIR in the mapserver config, is that library
used or the one in the GDAL config?

Thanks!
