Hi Jose,
The only way to find out the source of a segmentation fault is with a
debugger (e.g. gdb). I presume your GetMap requests run fine and it is
just this GetFeatureInfo request that fails? Would you be able to
provide a testcase for us to reproduce the error?
Perhaps you could also try to run this request at the command line to
confirm that you also get the segmentation fault:
/path/to/mapserv
"QUERY_STRING=map=.......&VERSION=1.1.1&TITLE=title&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=yyy&SERVICE=WMS&REQUEST=getFeatureInfo&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_xml&SRS=EPSG%3A2950&INFO_FORMAT=text%2Fxml&QUERY_LAYERS=yyy&BBOX=209601.108032%2C4995145.873053%2C455398.891968%2C5142254.126947&WIDTH=929&HEIGHT=556&X=428&Y=277"
(make sure you set the map=.... value in the command above to the value
of MS_MAPFILE set by your xxx_wms_en wrapper script)
If you also get a seg fault at the command line then you could try to
run the same request from inside 'gdb' and get a backtrace (command
'bt') to give us an idea of where the crash happens.

Hi,
After upgrading MapServer from 5.4 to 6.0 we get a 500 error in this query:

The map files were updated following the migration guide...
Any idea about where this is comming from?
Thanks,
