Bug #10368: GC mark miss on bindings

• Status: Closed
• Assignee: ko1 (Koichi Sasada)
• Target version: -
• ruby -v: ruby 2.2.0dev (2014-10-11 trunk 47881) [x86_64-linux]
• Backport: 2.0.0: DONE, 2.1: DONE

[ktsj (Kazuki Tsujimoto)]

以下のコードでSEGVすることがあります。
mに渡したブロックがGCされてしまうのが原因です。

def m
  binding
end

GC.stress = true
b = nil
tap do 
  b = m {}
end
GC.start
0.times.to_a
b.eval('yield')

ブロックに対応するProcオブジェクトをrb_binding_tに持たせるようにするパッチを添付します。
