New description:

 I have QGIS compiled from GIT, version 9ffedb4 on an amd64 machine.

 I'm trying '''qgis_mapserv''' with a simple project, but it crashes with
 '''segmentation fault''' or with this message:

 {{{
 qgis_mapserv.fcgi: checksum.c:150: crc32: Assertion `length >= 0' failed.
 Aborted
 }}}

 The problem exists also if I call the cgi-bin from the command line, like
 this (the QUERY_STRING must be on a single line):

 {{{
 cd /usr/lib/cgi-bin/toscana
 QUERY_STRING="SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap
 &BBOX=9.66321,42.2097,12.4125,44.4741&SRS=EPSG:4326&WIDTH=320
 &HEIGHT=200&LAYERS=province&FORMAT=image/png" ./qgis_mapserv.fcgi >
 pippo.png
 }}}

 The very same project gets rendered OK in QGIS 1.6.0.

 Can someone confirm that there is a bug?

 Here you can find the project with the shapefile:
