[mapserver-dev] strange behavior when size != gif size (UMN 5.4.2)

[Steve Lime]

I've been using shp2img. Just tried on another box with 5.4.2 with the attached result (verbatim mapfile I posted earlier).

Are you using the experimental PNG support by chance? Wouldn't think that would have an impact but I think that links 
MapServer against libpng. GD also links against libpng and perhaps there is confusion there if the versions are different?
