Description Soren Harward 2007-11-20 11:23:03 UTC

Poppler (the PDF library) causes libfontconfig to segfault in the FcConfigSubstituteWithPat function when I load certain PDFs that use non-embedded fonts.  I will attach a PDF that causes the problem.  Poppler itself is probably also at fault (and I will file a downstream bug, and add it to the notes here), but libfontconfig shouldn't segfault even if there's bad input.

Comment 1 Soren Harward 2007-11-20 11:31:07 UTC

Downstream bug (in Poppler) reported as bug number 13322 (https://bugs.freedesktop.org/show_bug.cgi?id=13322)

Comment 2 Gerben Vos 2007-11-22 12:32:22 UTC

New stack backtrace posted to the Poppler bug listed above.

Comment 3 Keith Packard 2008-01-13 17:03:38 UTC

Could you please attach the problematic PDF file?

Comment 4 Gerben Vos 2008-01-14 02:47:39 UTC

https://bugs.freedesktop.org/show_bug.cgi?id=13322 and http://bugs.gentoo.org/show_bug.cgi?id=199827 contain PDFs that reproduce this problem. Note that the issue seems to be Gentoo-specific and has been fixed (or rather, worked around) there.

Comment 5 Keith Packard 2008-05-03 19:29:12 UTC

The Gentoo bug makes it seem like this was an xpdf issue.
