我记得 CGDB 能够在它的 GDB 窗口中换行，但是在客户端的机器上，我几乎无法控制它，它只会剪掉所有不适合的东西——而在同一台机器上，纯 GDB 会换行.

我知道有问题的 GDB 窗口可以使用 PgUp/PgDn 垂直滚动，但问题是我无法查看 long std::string-s 的内容或查看类方法的全名。

那么，我该如何水平滚动它——或者恢复正常的换行模式呢？

PS：set width <any number>从 GDB 窗口中似乎没有帮助，被完全忽略；show width，当在之前调用时set width，输出 4 个字符后的值：

[UPD:]经过进一步调查，这看起来像是一个 CGDB 错误；修复（或仅仅是一种解决方法，如果没有 CGDB 开发人员审查就无法判断）就在这里。
