Issue #4870 has been updated by Motohiro KOSAKI.

Status changed from Open to Assigned
Target version changed from 1.9.3 to 1.9.x

ああ、担当者を設定し忘れていましたか。すいません。
ええと、ちょっと原因不明すぎて193に間に合う気がしないので遺憾ながら 1.9.x に設定しました。

以下調査状況

Macのlibcまわりのコードを読んだ感じだと _sigtramp はシグナルハンドラの本体
(というかユーザが登録いた本物のシグナルハンドラとsigreturnを呼ぶラッパ)なのでシグナルを
受信したんだろうな。と
で、シグナルハンドラの延長で signal_exec() が呼ばれているのはあからさまにおかしいので
メモリ破壊か、最適化の影響でバックトレースが取れなかったかなんですが、ソース見ると
signal_exec()から直接 rb_bug_errno() を呼ぶルートがなさそうなので最適化の影響を疑っています。

なので、rb_bug_errno()を呼んでるあたりのどこかでEINTR処理を追加したら良さそうなんですが、はてさて
