----------------------------------------
We're seeing some segfaults with ActiveRecord (rails 4-1-0 branch) when running on travis ci.

Haven't been able to reproduce yet, but we're seeing about a dozen build failures until now but still wanted to share it.
Maybe someone with more clue about that stuff has some idea what's going on and can point in some direction.
