fails on win32 system, when using the command shp2img on the map. The output map is 9K x 9K and it appears between the main gd image and the memory allocated in the raster resampling code the 32bit address space is exhausted. This might be ok, except that reasonable errors are not returned. Just a report that the layer failed to render.
It appears the raster rendering code does not report out of memory errors sensible, and in fact does not even check malloc() failures in some places it ought to. Problem experienced in 4.10 and 5.
