The error you get is similar to the one fixed in GDAL 1.6.1
(http://trac.osgeo.org/gdal/ticket/2896) but it is not the same one. It
is actually another instance of a similar problem in MapServer's
msDrawRasterLayerLow() source code. (Thanks to EvenR for pointing that
to us off-list).
Until a new release of MapServer with this fix is available, you could
possibly recompile MapServer with -U_FORTIFY_SOURCE or
-D_FORTIFY_SOURCE=0 in the CFLAGS.

Hey, I set the ubuntugis repo, but still, I got a overflow error, this
is what I got on Ubuntu installed:
ii libgdal1-1.6.0 1.6.1-1~jaunty Geospatial Data Abstraction Library
ii mapserver-bin 5.4.0-2~jaunty MapServer utilities
ii cgi-mapserver 5.4.0-2~jaunty CGI executable for MapServer
ii proj 4.6.1-5~jaunty Cartographic projection filter and library
I mean, I install all things from the PPA repo, but I still got the
overflow :S, thx for any answer, this is the debug from shp2img
