Cmd 将某些文本粘贴到irb控制台窗口会崩溃

当我自己粘贴以下文本时，它会使控制台窗口崩溃。在Taskmanager中，“cmd.exe”仍然显示，但我注意到在事件视图中同时出现了“conhost.exe”的应用程序错误。是否有一些已知的irb或windows 7错误会导致这种情况

ruby 1.9.3p392（2013-02-22）[i386-mingw32]

粘贴的文本：

  ffi_convention :stdcall

  enum :lvm, [:LVM_GETITEMCOUNT, 4100,
          :LVM_DELETEALLITEMS, 4105,
          :LVM_GETNEXTITEM, 4108,
          :LVM_SETITEMPOSITION, 4111,
          :LVM_GETITEMPOSITION, 4112,
          :LVM_ARRANGE, 4118,
          :LVM_UPATE, 4138,
          :LVM_GETITEMTEXTA, 4141,
          :LVM_SETITEMTEXTA, 4142,
          :LVM_SETEXTENDEDLISTVIEWSTYLE, 4150,
          :LVM_GETEXTENDEDLISTVIEWSTYLE, 4151 ]

  enum :parameter, [:GW_CHILD, 5,
                :LVA_SNAPTOGRID, 5,

                :SNAPTOGRID_OFF, 364997680,
                :WS_POPUP, 0x80000000L ]

我在另一台电脑上试过，但没有得到这些结果，我也试过重新启动。
