Description Jack Moffitt 2004-10-21 12:35:54 UTC 
The file Bug687290.ps from the nightly regression test is causing Ghostscript to
segfault for the normal raster test in both banded and unbanded modes for pkmraw
and r72.

Here is the commandline to reproduce:
gs -dQUIET -dNOPAUSE -dBATCH -K1000000 -r72 -dMaxBitmap=10000 -sDEVICE=pkmraw
-sOutputFile='Bug687290.ps.pkmraw.72.1' -dNOOUTERSAVE -dJOBSERVER -c false 0
startjob pop - <  '/home/regression/comparefiles/Bug687290.ps'
Comment 1 Ray Johnston 2004-10-22 11:06:00 UTC 
This file runs sometimes and not others. I determined that I can get a repeatable 
failure with a DEBUG build, using the -Z@\$\? option. This appears to be 
UMR related to the 'sbits' array having different elements initialized in set_ht_colors 
that are used in set_color_ht  (great names, huh?) 
 
Elevating to 8.50 release critical since UMR's that cause segfaults are *NOT GOOD*

Copying from Bug 687774 :
Running "pkmraw -r72 Bug687290.ps" on Windows got a crash in 
gx_render_ht_1_level due to  b_level = -131058, porder->levels[b_level] runs 
out the array range.

See bug #687805 for followup on where the copying of color procs when making a
targeted null device should happen.
