Bug #1267: DL::Handle#sym segfaults with nil
http://redmine.ruby-lang.org/issues/show/1267

起票者: Nobuyoshi Nakada
ステータス: Open, 優先度: Normal
カテゴリ: ext, Target version: 1.9.1
ruby -v: ruby 1.9.2dev (2009-03-11 trunk 22881) [i386-darwin9.0]

DL::Handle#symにシンボル名としてnilを渡すと代わりにRTLD_NEXTを使
うようになっていますが、RTLD_NEXTが渡せるのはシンボル名ではなく
て第一引数のハンドルのほうです。

ハンドルに該当するのはselfですが、もちろんnilは渡しようができな
いのでクラスメソッドを定義するのはどうでしょうか。

$ ruby -rdl -e 'p DL::Handle.new("libc.dylib").sym(nil)'
-e:1: [BUG] Segmentation fault
