We're running cgit-1.1 with git-2.10.4 at https://git.slackbuilds.org and are 
seeing
some reproducible segfaults.

root@git:/var/log# dmesg -T
[Wed Aug 16 01:14:23 2017] traps: cgit.cgi[2210] general protection ip:4515bd 
sp:7ffd787a9470 error:0 in cgit.cgi[400000+103000]

This can be reliably triggered (i.e. every time) with at least one particular 
link (I'll share it 
privately with cgit devs, but since I don't know if there's any security 
impact, I'm not going
to put it out on the list as yet).

I've applied 1b4ef6783a71962f8b5da3a23f283 and c699866699411346c5dba4064575
from git master since they appeared to address some segfaults, but apparently 
they were
unrelated to whatever it is that we're seeing. 

Aside from (obviously) sharing the reproducer, any tips on debugging this? We 
of course
have a strong preference for debugging tips that don't impact services on the 
machine,
but if needed, we'll do what we have to do...
