Core Dump PDF to PNG 7.0.8-38 - 7.0.8-42

Posted: 2019-04-22T08:13:11-07:00
by majokr
Alpine 3.9
Ghostscript: 9.26-r2
ImageMagick: 7.0.8.38-r0

PDF Example File: https://www.iso.org/files/live/sites/is ... t_2009.pdf
Other files also trigger core dump but not all

There were issues with ghostscript options -dFirstPage=1 -dLastPage=1 creating core dumps, but the underlying ghostscript command works in the patched version of 9.26. ( Older bug: https://bugs.launchpad.net/ubuntu/+sour ... ug/1806517 )

If you leave off the page restriction '[0]' all pages are processed successfully.

Command:

Code: Select all

 'magick -debug all test.pdf[0] test.png'
Output:

Code: Select all

Also had the same behavior on a builds of 7.0.8.42, 7.0.8.41, & 7.0.8.40 but the most recent alpine package from the repos is 7.0.8-38

Nevermind, ghostscript still seg faults on that file:
