Hullo!
I usually use the following command to join several PDF files in one :
gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=output.pdf input1.pdf input2.pdf
Hadn't have to do it for a while but today, I needed it and thus fired my script.
Blam! gs segfaults.
A quick internet search and I found this :
https://bugs.archlinux.org/task/22006
Though Arch related, while I'm running slackware64-current, the behaviour was exactly the same as mine.
In the above thread, one guy linked to a bug report which seems to be the culprit :
http://bugs.ghostscript.com/show_bug.cgi?id=691831
gcc 4.5.1, gs 9.00, x86_64, indeed, slackware64 seems to be exactly in that situation.
Would be great if Slack did apply this patch. :-)
