+Subject: [PATCH] Ensure a device has raster memory, before trying to read it.
+
+Bug #697676 "Null pointer dereference in mem_get_bits_rectangle()"
+
+This is only possible by abusing/mis-using Ghostscript-specific
+language extensions, so cannot happen in a general PostScript program.
+
+Nevertheless, Ghostscript should not crash. So this commit checks the
+memory device to see if raster memory has been allocated, before trying
+to read from it.
