Description keinbiervorvier 2003-10-30 16:07:04 UTC

this applies to current cvs HEAD as of 10/30/03

AFPL Ghostscript CVS PRE-RELEASE 8.12 (2003-08-18)

gs 8.12 on redhat 9 linux with gcc 3.3.1 fails to display the file at 

http://lanl.arxiv.org/ftp/exports/jb.ps

and exits with error:

gs: src/gxccman.c:574: gx_add_cached_char: Assertion `cc->pair == pair' failed.


AFPL gs 8.11 and GNU Ghostscript 7.05 (2002-04-22) don't have a problem to
display this file.

Cheers
Thorsten

patch

Initialize cc->pair field for the exterbal fonts, forgotten
during the switch to new TrueType interpreter (NEW_TT_INTERPRETER).

Comment 2 Alex Cherepanov 2003-11-02 18:43:01 UTC

The patch is committed to HEAD branch.

Example PS file for gxccman error message

With gs 8.13 (Solaris 7 SPARC), this bug still occurs with x11alpha for many
PS files, although no more with the example jb.ps. The same happens with
-sDEVICE=bit -dTextAlphaBits=4 -dGraphicsAlphaBits=4, and thus, also with
ps2epsi.
(The patch 003993 by Ray Johnston (Mon Jan 12 18:06:14 PST 2004) for gsdevmem.c

and gsdevmem.c has been applied.)
Assertion failed: cc->pair == pair, file ./src/gxccman.c, line 574
Example file "feuercall.ps" (made with xfig) is attached.

Comment 4 Hans Werner Strube 2004-02-27 07:20:56 UTC

In gs 8.14, the bug appears to be absent, for both x11 and bit devices.

Comment 5 keinbiervorvier 2004-02-27 08:14:25 UTC

I reported this problem in November 2003

current CVS HEAD (February 27, 2004) does not exhibit this problem.

Thanks
T.

Comment 6 Alex Cherepanov 2004-05-13 07:37:09 UTC

Assertion related to TT fonts was fixed by the attached patch.
Assertion related to alpha rendering is a duplicate of the bug 687241 ,
and it is also fixed now.
