I'm not sure 2014 counts as the "latest". :) My stock compiler is 4.9.2, and gcc-snapshot on Debian unstable is:

  gcc (Debian 20150516-1) 6.0.0 20150516 (experimental)
  [trunk revision 223239]

Both versions I listed above seem to work fine for me. Of course we can't definitively rule out git provoking undefined behavior in certain compiler versions, but short of more data, I'd say it's probably a gcc bug in 4.9.0 which has since been fixed.
