I've done some more investigation and found the seg fault happens with a
call to msDrawRasterLayerGDAL() according to gdb. I also found what is
tripping the core dump in the map file. I have an class with 'EXPRESSION
([pixel] > 0)' so mapserver does not draw black pixels. When I remove
this, it works fine although it has the black pixels I don't want. So,
it appears I'm doing something wrong with the EXPRESSION statement. Any
one have any ideas how to fix this or workaround it? Again, what I find
strange is that this works fine in MapServer 4.x but not 5.x.
Thanks for your help,

I have a php script that generates a png from geotiff tiles. The tiles
are indexed using gdaltindex. The php script works fine for MapServer
4.10.x but seg faults for version 5.x.x. Does anyone know of any
differences between version 4 and 5 that would cause this? Could it be
from an older version of gdal that the tiles are being generated with?
This happens in both RedHat Linux 4 as well as on our Solaris
machines. I can provide more details if someone can point me in the
right direction on where to look first for a problem.
Thanks is advance for any insight any one might provide!
