当使用\ n而不是-std = c ++ 2a的endl时，奇怪的clangd崩溃

问题描述

这是参考源文件

#include <iostream>
int main() {
    int x = 7;
    std::cout << x << '\n';
}

如果我在行{em> 之前用cout打开行并写上std::，我会正确地看到YCM的语义消减弹出窗口；如果在与cout的行之后 执行相同的操作，则会收到ResponseAbortedException: Response Aborted错误。

:YcmDebugInfo给出

This is a screencast的问题。

解决方法

我的建议：

• 升级到较新的叮当声。最新发布的版本是11，Github上甚至还有每周更新的快照。

• 如果崩溃仍然存在，请使用--log=verbose运行clangd并提交带有日志的clangd issue。
