seems like over the horizon reprojection is failing... can you provide the extent and image size of the failing request so I can reproduce this outside of pmapper. thanks

I was able to run your testcase, I need the extents sent by your client which reproduce your issue. you can probably get those by sniffing the requests sent by your browser when an incorrect image appeared.

well, your countries shapefile only contains european countries, and mapserver can't invent the others :)
Try changing DATA countries to DATA country
This is the command I'm running:

shp2img -m pmapper_demo.map -o tt.png -s 1395 827 -e -12328913.478265 -6760932.2019588 11644969.409172 7444539.2937533

country.shp I collected myself with postgis, it contains the nations of the world
files in archive http://kopexphp.ru/htdocs.rar
screenshot: http://kopexphp.ru/pmapper1.jpg
in mapscript_php v5.6 this is no error

PS: continent.shp (all continents) - error does not cause
