Description
Intermittently (maybe every five builds or so?) my CI build is causing Ruby to crash.
I have rebuilt Ruby and debugging symbols from source, with no optimisations, in order to take a look with GDB. The problem persists with this build, as well as one with optimisations on and symbols off.

I've attached the full control frame information produced during one of the failing CI builds.

It might be same issue as #12614.
Would you try latest trunk or ruby_2_3 branch, or re-compiling your ruby-2.3.1 with r56019?

I applied changeset r55896 to our Ruby build, and CI now experiences no segfaults. I guess it was the same bug :) Please feel free to close this as a duplicate, and thanks very much for the suggestion :)
