c - 运行 'finish' 命令时 GDB 退出

Question

我下载了 mingw-w64，这样我就可以编写程序并在家用笔记本电脑上对其进行调试，但是无论出于何种原因，每当我使用 gdb 调试程序并且我希望使用“完成”命令退出函数时， gdb 一直运行直到它从函数返回并退出，然后我返回到 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。
