Segmentation fault while running tests for latest Rails 4.2

Hi All,

I am trying to build Rails from source for the latest stable (4.2)
version
from the branch 4-2-stable; however I am facing issue while running the
tests.

I am getting a segmentation fault at ‘activesupport’ for rake tests.

Has anyone already seen this error before? Can someone help me fix this
test-case?

The details of error log are as below:

Platform I am trying on: Ubuntu 14.10

Rails Version: 4.2.3

Ruby Version: 2.2.2 & 2.1.6 (on both versions getting same trace)

Command used:

$ bundle exec rake test --trace
