运行 'finish' 命令时 GDB 退出

Question

我下载了 mingw-w64，这样我就可以在家用笔记本电脑上编写程序并对其进行调试，但无论出于何种原因，每当我使用 gdb 调试程序时，我希望使用 [=15 退出函数=] 命令，gdb 只是运行，直到它 return 从函数退出，然后我 return 到 shell 的提示符。我不知道是什么导致了这个错误，它特别烦人并且使调试变得非常困难，因为它迫使我在退出之前检查函数中的每一行（上帝禁止有循环）。有人以前遇到过这个错误吗？有解决办法吗？

Answer 1

看来这个问题是GDB 8.1版本内部的一个bug引起的。所以我又回到了 GDB 8.0，它似乎工作得很好。
