ghostscript-6.51-16 crash viewing font page
Last modified: 2007-04-18 12:38:38 EDT
I downloaded FontSheets.ps from http://www.glyphic.com/free/fontsheets/fontsheets.html and attempted to view it with "gs FontSheets.ps" with ghostscript-6.51-16. It dies when I attempt to move from the first to the second page by hitting return. Here's what it says when it dies: Error: /rangecheck in --stringwidth-- Operand stack: (FutoGoB101:Kanji) --nostringval-- false (VFlib Vector Font Library) FutoGoB101-Bold-Ext-H () --dict:12/12(ro)(G)-- 177.75 (abcDEFGHIJKLMNOPQRSTUVWXYZ) (&123) 141.75 (abcDEFGHIJKLMNOPQRSTUVWXY) 141.75 Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push 1 3 %oparray_pop 1 3 %oparray_pop 1 3 %oparray_pop .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- %array_continue --nostringval-- --nostringval-- %loop_continue --nostringval-- --nostringval-- --nostringval-- %array_continue --nostringval-- --nostringval-- --nostringval-- --nostringval-- %loop_continue --nostringval-- --nostringval-- --nostringval-- Dictionary stack: --dict:1026/1476(ro)(G)-- --dict:0/20(G)-- --dict:90/200(L)-- --dict:125/200(L)-- Current allocation mode is local Current file position is 16974 GNU Ghostscript 6.51: Unrecoverable error, exit code 1 I note the comment in the changelog entry for 6.51-2: "I know that there are going to be problems in the japanese code, and I need to turn on the cjk font map from adobe, but it /works/ at the moment." I wonder if perhaps this is one fo the referenced problems in the japanese code? I made this problem go away by commenting out all the uncommented lines in vflib/kconfig.ps. But then I got errors about GothicBBB. I made those go away by removing all of the files in /usr/share/ghostscript/Resource/CIDFont. Then I was able to use FontSheets.ps, until I attempted to add "loadallfonts" right after "%%BeginProlog", at which point I got this error, which I don't know what to do about. Note the third argument on the stack, which seems to have some sort of data corruption in it.

Seems to be kanji-related.
Still happens in 6.53.
Happens in 7.05-3 too (from rawhide).
The sample file is incorrect. The file is not aware of Asian fonts and CIDFont-CMap interaction. The error happens when the file attempts to interpret a string of 25 characters (odd number) in double-byte encoding.
So, NOTABUG?
Yes, Ghostscript correctly detects the error in PS program.
