mapserver segfaults on x68_64 intel xeon

[Alessandro Pasotti]

Hello,

I've compiled latest mapserver and all dependencies (gdal, proj, geos etc.) 
from scratches on a 64bit linux machine, build process went fine, but the 
resulting executable segfaults (the mapfile is ok, tested on other machines):


(gdb) set args -all_debug 9 -m /maps/appalto_26.map
(gdb) run
Starting program: ./shp2img -all_debug 9 -m /maps/appalto_26.map
[Thread debugging using libthread_db enabled]
[New Thread 46912537641984 (LWP 11768)]

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 46912537641984 (LWP 11768)]
0x00002aaaac518e40 in rawmemchr () from /lib64/tls/libc.so.6

The same happens with the cgi and php_mapscript:
[Fri Mar 02 08:08:58 2007] [error] [client 82.52.86.193] Premature end of 
script headers: mapserv
[Fri Mar 02 08:09:23 2007] [notice] child pid 11473 exit signal Segmentation 
fault (11)

Any idea on how to solve this?

Many thanks in advance.
