Hello Alexandre,

If I was in this situation I would:

- try to duplicate it with an easy shp2img command (I can locally, using
gmap75 mapfile and setting the projection of the grid layer to 3978
instead of 4326)
- then, once you get that crash with that easy command (yup I get the
crash with MS 6.0.3), I would start to comment all those parameters in
your actual GRID object
- for me, I found that once I commented the M*INTERVAL parameters I was
able to get a valid map image with grid lines nicely labelled in meters

I think there is a ticket/issue here so I think it would be nice to
package a little test case that throws this crash.

Happy first day of summer!  (or the best 5-à-7 day of the year!)
