setlocale卡在Windows上

Question

setlocale(LC_ALL, "uk-UA")有時會因為未知原因而掛起/死鎖。 調用堆棧是：

有時它有效，但有時它永遠不會從它返回。 我無法確定原因。 我使用Visual Studio 2015和Windows 7。

這是Universal CRT的TH1版本（10.0.10240）中的一個錯誤。 該錯誤已在Windows 10 November Update（TH2）版本（10.0.10586）中修復。

您可以從https://dev.windows.com/en-us/downloads/windows-10-sdk下載並安裝更新的Windows 10 SDK。 此SDK包含靜態通用CRT庫，調試通用CRT DLL（ucrtbased.dll等），以及用於應用程序本地重新分發的零售通用CRT DLL。

您可以從https://www.microsoft.com/en-us/download/details.aspx?id=50410下載更新的通用CRT可再發行組件。 它們包含更新的零售Universal CRT，用於在系統目錄中進行集中部署。
