I've got an image which causes giftext from giflib 4.1.4 to segfault along with a patch which fixes the issue. The patch comes from the FuzzyOCR guys and is one of the things which is holding up bug 154392, although I'll probably add the FuzzyOCR ebuild with a warning that some images may cause a segfault until this bug is fixed.

you should really take this to the upstream giflib mailing list ;)

Created attachment 108125 [details] giflib-4.1.4-r2.ebuild Here is an ebuild that applies the patch.
Created attachment 108127 [details, diff] updated patch Here is an updated patch to go with my ebuild. The directories were off for use with epatch
should be fixed in media-libs/giflib-4.1.6, which will go stable soon.
