Bug #15221: Segfault in Ruby VM
https://bugs.ruby-lang.org/issues/15221

* Author: jmreid (Justin Reid)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin18]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
Ruby is segfaulting randomly for me on MacOS 10.14 (18A391).

I don't have a script to reproduce the error as it seems to pop up randomly. But I was able to grab the stack trace (attached). It appears to be related to GC.
