Bug#490080: cupsys: [arch armv5tel]: pstoraster crashes on signal 11
Package: cupsys
Version: 1.2.7-4etch3
Severity: important
*Important*
I post this patch against Cupsys, while I do not handle
the complexity of print process.
My guess is that the bug comes from gs-esp (up-to-date, too).
ii gs-esp 8.15.3.dfsg.1-1etch1 The Ghostscript PostScript interpreter - ESP version
This bug do not affects my i386 box, but only my NSLU2 one (arch armv5tel).
Unfortunately, the last will be my media server, including printing...
*SO*
while I try to print (eg: test page from cups http frontend),
I got nothing.
/var/log/cups/error_log:
E [09/Jul/2008:18:06:08 +0200] PID 3128 (/usr/lib/cups/filter/pstoraster) crashed on signal 11!

"MFG:EPSON;CMD:ESCPL2,BDC;MDL:Stylus Photo EX;CLS:PRINTER;�
However, I tried several things:
printserver:/# ink -p usb

=> WORKS!
tom@printserver:~$ file hosts.ps
hosts.ps: PostScript document text conforming at level 3.0
tom@printserver:~$ cat hosts.ps | foomatic-rip -P epson > /dev/usb/lp0
=> prints the raw postscript file...
$ /usr/bin/gs-gpl -sDEVICE=stcolor -sOutputFile=hosts.epson hosts.ps
$ cat hosts.epson > /dev/usb/lp0
=> pretty print (in landscape, with header and frame) my /etc/hosts
tom@printserver:~$ /usr/bin/gs-esp -sDEVICE=stcolor -sOutputFile=hosts.epson hosts.ps
Segmentation fault
tom@printserver:~$ /usr/bin/gs-esp
Segmentation fault
So, I thing the error might come from here, while I'm unsure.

I can send the completes strace and ltrace on demand.
