Bug 104540 – media-gfx/imagemagick - libfpx causes mogrify segfault on converting fpx file to other format

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Francisco J. Perez 2005-09-01 21:07:04 UTC]

Imagemagic-6.2.2.3-r1 
Libfpx-1.2.0.9
Gentoo 2005.1
(2)Intel Pentium III Xeon 1.0 GHz

When attempting to convert from an fpx image to another image format (tried
converting to png, gif and jpg) using Imagemagick's mogrify tool, mogrify
produces a segmentation fault.  As per imagemagic.org
(http://studio.imagemagick.org/pipermail/magick-bugs/2003-January/001033.html),
this problem is with libfpx, however I cannot find any evidence that this
problem has been fixed.  Cannot find other mentions of this specific problem or
a possible fix however there is a newer version of libfpx on the portage tree
which is still masked (1.2.0.12) and a another newer version on the imagemagick
website (1.2.0.13).       


Reproducible: Always
Steps to Reproduce:
1.frank@stevens ~/pictures/balboa_terminal $ mogrify -format png *.fpx
2.
3.

Actual Results:  
frank@stevens: ~/pictures/balboa_terminal $ mogrify -format png *.fpx
Segmentation fault


Expected Results:  
The images in the directory should have been converted from fpx format to png
format and then saved as new files with the extension changed to png.

I found the source of libfpx @
ftp://ftp.imagemagick.com/pub/ImageMagick/delegates/  
and after verifying the changelog, I cannot find any mention of this problem,
but on the other hand, I'm not a programmer and really don't know what I am
looking for.

Could you attach one of your fpx files? I can't reproduce it with mine.

See above; we need some sample files to reproduce this.
