The standard regression file vtm2k.pdf (attached) renders to a complete black image when ripped with Ghostscript r8664 or later; previous revision produce a half white/half light yellow image, the same as Acrobat Reader. The command line I'm using: bin/gs -sDEVICE=ppmraw -o test.ppm ./vtm2k.pdf
Created attachment 3967 [details] vtm2k.pdf
It should be back to how it was prior to r8664. A new bug was issued related to this output compared to AR (dark versus light yellow). bug 689808
