I'm not replicating this with the provided GIF. Can you say which version of gifsicle you're using and which platform?
Thanks for the quick response! We're using gifsicle 1.96 on various versions of Debian (mostly 10 and 11). Please tell me if you need any other details!
Later edit: here's more details:
/tmp/gifsicle # more /etc/debian_version
11.9
/tmp/gifsicle # gifsicle --version
LCDF Gifsicle 1.96

I guess we have a version that hasn't been publicly released yet and if I remember well, it contains a bug fix that we reported sometime last ~week~ year. Thanks!
After speaking with my colleague @simondud, this is the issue that was fixed in this commit. After the commit, we took the master branch, built it and that's what we currently use (and returns the segmentation error above).
Please tell me if you need more details. Thanks!
P.S. We are happy to donate to the development of this project, so please tell us if you have any system where we could financially contribute to your project.
Hi @pdobrescu, I think I misunderstood your comment. I thought you said that the current master branch does not crash, but you're saying it does. Let me look again.
On x86-64 Amazon Linux, I see no segmentation fault. This is compiled with -fsanitize=undefined -fsanitize=address. The sha256sum of the input GIF is 678379dab089044e55de5baa3219411d84642ead6ae12cb2a48ab70db09a2aa6; I am using -O3 --lossy=10 --colors=256
and commit 338d286490750a4cc1ba728ddd4588bf46027ff7.
So I do need more details. Feel free to use email for that, or here is also fine.
Hello, and thanks for the very useful tool!
We use it to compress GIF files and for some files, we get a segmentation fault error when running it like this:
gifsicle -O3 --lossy=10 --colors=256 /path/to/source.gif -o /path/to/destination.gif
Here's an example file that returns this error:
Any ideas/suggestions would be more than welcome! Thanks!
