Rufus調度程序中拋出Ruby代碼異常

我在執行無限循環中的功能的debian linux上執行控制器。除此之外，我正在使用Rufus Scheduler來安排一個在特定時間段後運行的功能，比如說1分鐘。一旦功能執行魯弗斯正確，我得到以下錯誤Rufus調度程序中拋出Ruby代碼異常

這是一個的被從機庫引發的異常，不紅寶石本身。它看起來像的根本原因可能是在tiny_tds寶石你使用：

/usr/local/rvm/gems/ruby-2.1.0/extensions/x86_64-linux/2.1.0/tiny_tds-0.6.1/tiny_tds/tiny_tds.so(+0x44f1) [0x2b1907ff24f1] result.c:89

你試過升級到tiny_tds更高版本，看看問題是否仍然存在？

編輯：我看到它是最新版本;也許用tiny_tds維護者提出這個問題 - 請參閱https://github.com/rails-sqlserver/tiny_tds

我檢查了文檔並嘗試使用--with開關安裝免費的tds，但錯誤仍然存在。這是寶石或寶石的不兼容性，還是可能導致代碼錯誤，導致發生這種異常。 –

看起來這是一個本地代碼中的錯誤，而不是gem本身，這就是爲什麼我建議把它與維護者聯繫起來。 https://github.com/rails-sqlserver/tiny_tds/blob/master/ext/tiny_tds/result.c#L89是引發錯誤的行，它看起來像上面的GET_CLIENT_USERDATA返回空引用 - 當這是取消引用段錯誤被提出。 – mcfinnigan

然後我應該糾正這個問題。 –
