Description Ralph Giles 2008-07-10 15:31:57 UTC 
The following ps3cet files fail with a segfault with the pkmraw device:
12-02.PS, 12-07A.PS, 12-07C.PS.

Example command line:

bin/gs -sDEVICE=pkmraw -o /dev/null ../tests_private/ps/ps3cet/12-07C.PS

The crash also occurs when invoked in CET mode:

./bin/gs -q -I$HOME/fonts -dQUIET -dNOPAUSE -dBATCH -K1000000
-dMaxBitmap=30000000 -sDEVICE=pkmraw -r600
-sOutputFile="|md5sum>/tmp/12-07A.PS.md5" -dJOBSERVER lib/gs_cet.ps -
</b/02/atfxsw01/tests_private/ps/ps3cet/12-07A.PS

And at 600 dpi.

gdb reports the crash is inside the COLOR_SET_GRAY macro called from gximono.c:496
Comment 1 Ralph Giles 2008-07-10 15:32:43 UTC 
Setting priority for segfault. Reproduced on x86 linux (cluster) and x86_64 linux.
Comment 2 Alex Cherepanov 2008-07-11 13:59:41 UTC 
The crash first appears in the rev. 8829.

Move the interpolation image class from the ps2 dev to the core graphics
library so it is available to all languages.
Comment 3 Alex Cherepanov 2008-07-11 14:55:54 UTC 
Apparently, 2_fracs image class was left out.
This fixes the crash for me.
