Gustav,

A few ideas to get you started:

1) if you plan to debug mapserv make sure you ./configure --with-debug
2) you might start debuging using shp2img
    a) start by getting shp2img to run with some command line options
    b) gdb shp2img
       break main
       run <commandline options>
3) to debug mapserv you can use
    a) gdb mapserv
       break main
       run QUERY_STRING='url-params-after?'

Try some of these and see if you get any further.
