6.5.1-0 convert seg faults on multipage pdf

[mathog]

Using the sunfreeware build of 6.5.1.0 on a Sparc Solaris 8 system convert consistently segfaults when it acts on a multipage
PDF file that contains images. In the following this is demonstrated by converting 3 pages (fails), each page one a time (success),
then 2 pages (fails):

Code: Select all

# gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -dFirstPage=8 -dLastPage=10 -sOutputFile=three.pdf  many.pdf
# convert -compress JPEG three.pdf convert3.pdf
Segmentation Fault (core dumped)
# gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -dFirstPage=8 -dLastPage=8 -sOutputFile=one.pdf  many.pdf
# convert -compress JPEG one.pdf convert3.pdf
# gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -dFirstPage=9 -dLastPage=9 -sOutputFile=one.pdf  many.pdf
# convert -compress JPEG one.pdf convert4.pdf
# gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -dFirstPage=10 -dLastPage=10 -sOutputFile=one.pdf  many.pdf
# convert -compress JPEG one.pdf convert5.pdf
# gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -dFirstPage=8 -dLastPage=9 -sOutputFile=two.pdf  many.pdf
# convert -compress JPEG two.pdf convert6.pdf
Segmentation Fault (core dumped)

Here is gdb output for the failed two page conversion:

Known bug? Fixed in a more recent version? Ironically I just upgraded from 6.2.5, which didn't have this problem.

As an aside, the single page conversions came out 2X bigger than the input.

Thanks.

Note added: the previous version was carefully removed before the new one was installed. Everything that I could identify as
being part of the old ImageMagick was deleted from /usr/local.

We believe that is a known bug and is fixed in recent releases of ImageMagick. The current release is version 6.5.8-10.
