Aha! It looks like the combination of cgi map_layer_class_expression and the projection causes MS to generate an error!

I have a MAP level PROJECTION object, and one layer with a different PROJECTION than the others ... (The map is in an LCC projection, and the layer in geographic). This used to work fine in 3.6.6, but now I get "msDrawMap(): Image handling error. Failed to draw layer named 'featureannotate'." ... That layer being the one in geographic that should be getting reprojected. If I take out the PROJECTION parameter of the layer, no errors! I tried moving it's definition with the layer, which didn't change anything ... I also tried using both epsg codes and in-line definitions, which also didn't help :( I was using PROJ 4.4.5 ... Upgraded to 4.4.9 ... That didn't help. I re-compiled MS just to be safe, the problem remains ... I have a WMS server running off the same setup without complaints (including reprojection). The shapefile looks ok, shpdump/shptest and dbfdump didn't produce anything out of the ordinary ... Any ideas? Thanks!
