Segmentation fault

[Dan Ringwalt]

I noticed a segmentation fault when running Ghostscript on a large PDF. The PDF can be downloaded from here: http://petrucci.mus.auth.gr/imglnks/usimg/a/ab/IMSLP55701-PMLP05948-WTC1-Mugellini-no_1-12.pdf

The command line options I am using are:

gs -dBATCH -dNOPAUSE -o 'out%d.png' -sDEVICE=pngmono -r100 IMSLP55701-PMLP05948-WTC1-Mugellini-no_1-12.pdf

and it seems to fail on page 19. The first 18 files are created successfully.

I am using Ubuntu 12.04.1 LTS and ghostscript version "9.05~dfsg-0ubuntu4.2". I've tested on both x86_64 and i386.

I made a PDF only containing the page which causes the problem, and this PDF also causes the segmentation fault when running e.g.:

gs -dBATCH -dNOPAUSE -o page.png -sDEVICE=pngmono page.pdf

I have also ran same command on same PDF and its creating problem on page 19. Otherwise I tried an IBM Redbook http://www.redbooks.ibm.com/redbooks/pdfs/sg247738.pdf which is of 5.8MB and 318 pages and it worked fine.

Thank you very much for the bug report.

Please follow the upstream bug report and answer questions of the Ghostscript developers there. Thanks.

Tried to get output of Valgrind but it crashed on Page 7 :)

Thanks Till, the patch there seems to fix the problem!
