This is the http clone interface generated by cgit, and a quick test gives me an identical segfault, while `git clone http://git.sv.gnu.org/r/xboard.git` succeeds. I can only guess, but maybe this has something to do with caching in cgit:

Hmm, the packs looks ok so maybe the problem is related to our usage of libcurl after all...
