Ciao Luca,
I am wondering also if you tried to access the PostGIS data through
ogrinfo yet (to confirm there is no data issue). Note that I'd
recommend GDAL 3.4.2, PROJ 8.2.1 with MapServer-main.
ogrinfo -ro PG:"user=xxxx password=xxxx host=127.0.0.1 port=5432
dbname=xxxx" table -summary
Then, follow along the debugging document (
https://www.mapserver.org/optimization/debugging.html ) and add the
following inside your MAP object in mapfile:
CONFIG "CPL_DEBUG" "ON"
CONFIG "CPL_TIMESTAMP" "ON"
CONFIG "PROJ_DEBUG" "ON"
Then re-retry map2img with -all_debug 5, and look for the full SELECT
query made to your database, and run that same query inside psql
commandline.

Hi all,
I'm getting "Floating point exception" error running shp2img, also
running with the debug option I don't get any other information.
The mapfile read data from PostGIS database, and If I use the same
mapfile with different database with the same tables I don't get this
error, so I think the problem is in the data but I don't know
where/what investigate
thanks in advance
