giftext-segfault.patch


maybe related patch needed ?

It would be nice if this patch was merged since the segfault occurs quite often
with spam images scanned by SpamAssassin+FuzzyOCR.

From what I can see this isn't the same thing as the giftext problem and hence
that patch won't work.

I've tried a gif that causes giftext to segfault with giffix without any
segfaults and the same goes for brokken.gif which doesn't cause giftext to
segfault.

is this bug still needed to fix ?

is this bug still a bug ?
