No I can't because ref is required by therubyracer gem, which is needed for rails assets precompilation. So I tried updating ref gem.

After running `bundle update therubyracer`, the updated gems are:
 - therubyracer from 0.11.3 to 0.12.0
 - libv8 from 3.11.8.17 to 3.16.14.3
 - ref from 1.0.2 to 1.0.5

It seems to fix it: I tried multiple times and it has always worked. I tried with these rubies:
 - ruby 2.1.0 (ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-linux])
 - ruby 2.1.1 (ruby 2.1.1p2 (2013-12-31 revision 44467) [x86_64-linux])
 - ruby 2.2.0 (ruby 2.2.0dev (2014-01-08 trunk 44527) [x86_64-linux])

I do not know if the culprit is ref, libv8 or therubyracer. I joined the Gemfile.lock files: one when it segfaults and one when it works.

----------------------------------------
I got a stacktrace while capistrano was deploying our rails app to our server. We switched to ruby 2.1.0 recently. It worked on my dev station, not in staging.

I attached the ruby stderr as output by capistrano and every line was prepended with '*** [err :: hostname.com] '. I removed them for clarity. It looks like some output has been modified by capistrano too.

If you need further data, please tell me.
