[maplab-users] Segfault when working with raster data (GeoTIFF)

[Dan Boitnott]

I get a Segmentation Fault when I use a GeoTIFF layer.  I tried my own 
code and then some from the tutorial.  Here's my configure command:

./configure --prefix=/opt/mapserver --with-php=/usr/include/php/main 
--with-gd --enable-force-freetype1 --with-proj=/opt/proj 
--with-wmsclient --with-gdal=/opt/gdal/bin/gdal-config --with-jpeg 
--with-zlib --with-png --with-xpm --with-libiconv --with-tiff 
--with-ogr=/opt/gdal/bin/gdal-config

Here's the GDB back-trace:

(gdb) run "QUERY_STRING=map=/var/www/html/tutorial/example1-5.map&mode=map"
Starting program: /home/dboitnot/download/mapserver-4.0.1/mapserv 
"QUERY_STRING=map=/var/www/html/tutorial/example1-5.map&mode=map"
