Description Yue Luo 2003-12-16 09:42:05 UTC 
For Ghostscript 8.12
I got a document from SPARC.  It is downloadable from
http://www.sparc.com/standards/SCD.2.4.1.IS.ps.Z
When I try to open it, I got the following error

************************
Assertion failed!
Program: C:\gs\Ghostgum\gsview\gsview32.exe
File .\src\gxccman.c
Line: 574

Expression: cc->pair==pair

For information on how your program can cause an assertion failure, see the 
Visual C++ documentation on asserts.
********************************

Version 8.00 works fine.

Probably, this is a duplicate of the bug 687116 fixed earlier.
I can not duplicate the problem in any recent version of Ghostscript
(8.11, 8.12. 8.13) on Windows or GNU/Linux.
Comment 2 Yue Luo 2003-12-17 06:31:23 UTC 
I downloaded the 8.12 version from
ftp://mirror.cs.wisc.edu/pub/mirrors/ghost/AFPL/gs812/

This version has the bug on both Windows NT and Windows 2000.  Do you have a 
new fixed version downloadable?

Thanks.

I tried this same 8.12 on Win 2000 and cannot make it fail from the command
line, but can make it fail when invoked from gsview 4.4

It works from the command line, so this is a temporary work around.

Comment 5 Peter Mueller 2003-12-25 02:51:08 UTC 
I'm testing 8.12, too. The error occurs with 

gs -sDEVICE=x11alpha xxx.ps

gs: ./src/gxccman.c:574: gx_add_cached_char: Assertion `cc->pair == pair' failed.
Comment 6 Igor Melichev 2003-12-31 02:32:05 UTC 
The problem reproduces with 

    gs -r72 -dTextAlphaBits=4 -sDEVICE=ppmraw -sOutputFile=o.ppm 
CompareFiles\017-01.ps 

I've made a patch, now testing.

This file also causes the same error in 8.14

Should this be reopened?
