Hello

Got many of those:

*** Error in `/home/py/.rvm/gems/ruby-2.0.0-p643@global/bin/bundle': free(): invalid next size (normal): 0x00000000042d6a10 ***
Abandon (core dumped)


Making a bundle install will take 10 restart because it is ofter crashed with that error.
Restarting the command do the job.
