suggested that SegFault problem could be traced to mapserver's shp2img,
so we tried shp2img and did get that segfault crash. When we tried using
gdb to 'debug' the shp2img util with the same mapfile, we found it
crashed on tif_read, here is the message before it died,

I hope i have explained my problem clearly. Any help/hint will be
greatly appreciated! By the way, almost all mapserver versions above
4.0.1 have been triedwith the same configs as below and failed exactly
the same way.

Here is my mapserver config:
