I am trying to write an own driver based on the bmpsep1 device. I had some core dumps and was thinking that on my side must something wrong. The only difference I found was that my default resolution is 600dpi. After at least one day of debugging I tested with the bmpsep1 driver and had the same problem there. With the default resolution the page renders but when I bump up the resolution to 600dpi or 1200dpi I always get a core dump. Tested this on various OS and GS versions: Tested on Ubuntu 9.10 x86 with gs 8.70 and gs 8.64 (developer machine) gs -dBATCH -dNOPAUSE -sDEVICE=bmpsep1 -r600 -sOutputFile=altona.bmp altona.pdf (core-dump) gs -dBATCH -dNOPAUSE -sDEVICE=bmpsep1 -sOutputFile=altona.bmp altona.pdf (ok) Tested on Ubuntu 9.10 x86 with gs 8.70 (other machine) gs -dBATCH -dNOPAUSE -sDEVICE=bmpsep1 -r600 -sOutputFile=altona.bmp altona.pdf (core-dump) gs -dBATCH -dNOPAUSE -sDEVICE=bmpsep1 -sOutputFile=altona.bmp altona.pdf (ok) Tested on FreeBSD 7.0 with gs 8.64 gs -dBATCH -dNOPAUSE -sDEVICE=bmpsep1 -r600 -sOutputFile=altona.bmp altona.pdf (core-dump) gs -dBATCH -dNOPAUSE -sDEVICE=bmpsep1 -sOutputFile=altona.bmp altona.pdf (ok) Tested on FreeBSD 5.5 with gs 7.07 gs -dBATCH -dNOPAUSE -sDEVICE=bmpsep1 -r600 -sOutputFile=altona.bmp altona.pdf (ok)

Next time, I request that the valgrind spew be put into a separate attachment, preferably compressed with gzip or lzma. I have reproduced this and the problem is in one of my areas -- clist. The reason that this is resolution dependent is that it switches over to clist mode. The problem is the plane extraction device and it's interaction with the clist. This device is not used in page buffer mode, so a work around is to force page buffer mode using -dMaxBitmap=40000000 (at 600 dpi) or -dMaxBitmap=160000000 (at 1200 dpi). The debug output posted in comment #4 shows what I observed. The clist_fillpage is being called during the replay of a band (when the clist is in reader mode).

The problem is that the plane_extract device is using some 'gx_forward' procs for painting, but these are hooked to the 'target' device, NOT the buffer device's methods. We either need to use the 'gx_default' procs for these newer painting methods, or add plane_* procs that do the special optimized forwarding the the underlying buffer/mem device (plane_dev in those procs). The optimization consists of using reduce_drawing_color to determine if the color used affects the particular plane selected, and then calls the mem device OR the default handling. Fixes in test.
Fixed (as described previously) in commit dba8f75
oops. Forgot to close the bug as FIXED.
