[ruby-core:65248] [ruby-trunk - Bug #10282] Reproducible segfault when inspecting this method

Issue #10282 has been updated by Eric Wong.

File 0001-object.c-rb_class_real-do-not-dereference-0-VALUE.patch added
Category set to core
Target version set to current: 2.2.0
Backport changed from 2.0.0: UNKNOWN, 2.1: UNKNOWN to 2.0.0: DONTNEED, 2.1: REQUIRED

This looks to be a simple dereference bug.
However, this is my first time looking a prepend so maybe there's a subtle
behavior change I missed.

"make check" and rubyspec passes, at least.

The example code can be found here (in this exact comment): https://github.com/pry/pry/issues/1299#issuecomment-56389004

I have taken the time to reduce it as far as this. It should be easily reproduced on other systems/versions now.
