Looks like the only “normal”(ish) word that has the gif string is fungiform, and even that has both hard/soft g listed as pronunciations. There are also apparently a few long words like spongiferous and some biologic classes (as opposed to (eg) species) ending in -formes that happen to end in -giformes (like Archaeopterygiformes). But I wouldn’t expect too many people to have those in their pocket during a discussion of -gif- words.
