Description Boris Folgmann 2003-03-03 11:24:12 EST

Description of problem:
I regularly use netpbm-tools for making non-interlaced GIFs interlaced. With
three new pictures I get a segmentation fault. With my old images it still works.

Version-Release number of selected component (if applicable):
netpbm-progs-9.24-3

How reproducible:
Always, see below

Steps to Reproduce:
1. giftopnm silver_border.gif | ppmtogif -interlace >silver_border_interlaced.gif
    
Actual results:
ppmtogif: computing colormap...
ppmtogif: 29 colors found
Segmentation fault


Expected results:
giftopnm works, but pptogif dumps core

Additional info:
I attach the picture for you.

Comment 2 Boris Folgmann 2003-03-03 11:36:03 EST

It seems to be a problem of the -interlace code, because it works without these
option, but of course that is not what I want to have.

Comment 3 Boris Folgmann 2003-07-22 12:57:42 EDT

Same problem with RedHat 8.0, netpbm-progs-9.24-9.80.2.

Comment 4 Phil Knirsch 2004-02-09 10:41:42 EST

Fixed in latest netpbm-10.19-2 available via rawhide.

Read ya, Phil
