Bug #13236: Ruby segfault
https://bugs.ruby-lang.org/issues/13236#change-64600

* Author: Gondolin (Damien Robert)
* Status: Closed
* Priority: Normal
* Assignee: shugo (Shugo Maeda)
* Target version: 
* ruby -v: ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
* Backport: 2.2: DONTNEED, 2.3: DONE, 2.4: REQUIRED
----------------------------------------
I have a program that segfault under certain conditions. It does not happen often, so it is hard to get the segfault.
The code is in https://github.com/DamienRobert/drain
You can run 'rake test' to (sometime, not often) get the core dump. I was able to get the coredump across different computers and different ruby versions.
In the tests I construct a graph with a cyclic path, so there is probably a bug in the gc when there are cyclic dependencies.

I join a coredump (compressed with xz), here is the backtrace (not very usefull because I did not compile ruby with debugging symbols):

```
Core was generated by `/usr/bin/ruby -w -Ilib:test -I/usr/lib/ruby/gems/2.4.0/gems/rake-12.0.0/lib /us'.
