What kind of GIF library did you use before this started to happen?
Was it an older version of giflib, or libungif?

Are you sure the header files you used for building Emacs against
giflib are consistent with the library? Latest versions of giflib use
different signatures of several functions used by Emacs, creating a
binary incompatibility with previous versions, so if you are using
headers that specify old signatures, you will get crashes.
FWIW, I'm using giflib 5.0.5 (not on GNU/Linux, though) with Emacs
without any problems.
