[Swftools-common] Bug report: pdf2swf says Couldn't load glyph and segfaults

[Oskari 'Okko' Ojala]

Hello,

the other problem I have is this one. Pdf2swf seems to fail to load some 
glyph(s) and then segfaults. As with the other problem I just reported, I have 
experienced this with a small number of some other pages too (but not the 
same). Most pages get converted normally. The amont of glyphs that fail varies 
from just 1 to about 20 per page, depending on the page.

With the page I am providing as a sample I don't get the "Couldn't load glyph" 
error when using the latest development version, but I do get the Segfault.

I have tried this with both freetype-2.1.4-4.0 (from Red Hat) and freetype 
2.1.10 (compiled from source).


Description of problem:
Swftools gives "Couldn't load glyph" error (0.7.0 does, not dev) and then 
segfaults. No swf file is generated.


Steps needed to reproduce:
1. Configure, make and install swftools.
   My swftools has been configured with "--disable-lame", but I don't
   think the issue is related to that.
2. wget http://www.frantic.com/okko/swftools-bugs/clg_segfault/clg.pdf
3. pdf2swf clg.pdf --pages=1 -o clg.swf
