在Windows上使用gdb调试MinGW程序,而不是在断言失败时终止

Question

如何在窗口上设置gdb,以便它不允许断言失败的程序终止？我打算检查程序中的堆栈跟踪和变量.

例如,g++ -g test.cpp -o test在gdb中运行使用MinGW编译的test.cpp程序:

#include <cassert>
int main(int  argc, char ** argv) { assert(1==2); return 0; }

得到:

$ gdb test.exe

(gdb)

我希望能够阻止程序立即终止,就像Visual Studio的调试器和Linux上的gdb一样.我做了一个搜索,发现了捕获信号的一些东西,但我似乎无法找到关于如何设置gdb来做到这一点的好帖子.

Answer 1

发现断点可以放在.gdbinit带有以下行的文件中:

set breakpoint pending on
b exit

这消除了为Windows输入yes的需要.

Answer 2

只需在退出时设置断点:

(gdb) b exit
