rugged 0.27 causes a segfault in ruby during gdk update on Arch Linux
I've been learning how to use the gitlab dev kit and recently ran into some trouble. I pulled the lastest master into my fork of gitlab-ce and gdk update stopped working.
Specifically, bundle exec rake gettext:compile segfaults.
/home/mike/.rbenv/versions/2.3.6/lib/ruby/gems/2.3.0/gems/rugged-0.27.0/lib/rugged/rugged.so: [BUG] Segmentation fault at 0x00007efd7b60cea0
ruby 2.3.6p384 (2017-12-14 revision 61254) [x86_64-linux]If I downgrade to rugged-0.26 then bundle exec rake gettext:compile runs without crashing.
I think this may be a library incompatibility. I'm running Arch Linux. The crash is shortly after it finishes loading libraries.
