Issue #10062 has been updated by Nobuyoshi Nakada.

File bug-10062.txt added
Description updated

Seems the `Queue` instance is not initialized properly.
Probably, `Queue#initialize` is overridden somewhere?

$ ruby -rthread -e 'class Thread::Queue; def
-e:1: [BUG] Segmentation fault at 0x00000000000008

Backport #10062: Segfault involving Queue

* Author: Fred Mitchell
* Status: Feedback
* Priority: Normal
* Assignee:
Pushing an object onto a `Queue` instantiation causes a segfault. This
was seen on Ruby versions 2.1.1 and 2.1.2

In the interests of being able to completely reproduce the environment
in which this happens, I have included detailed instructions here.

1. Clone (yes, the
devready branch)
2. In its root do "rake install" to install the gem
3. Clone
4. In its root do "rake install" to install that gem
5. Clone
(yes, the devready branch)
6. Go to the root of that and
7. Run "bundle update"
8. Run "neat run xor"
9. It should segfault almost immediately.
