----------------------------------------
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 onand can point in some direction.
