c - 使用调试器 gdb 时出现未知结束信号

Question

我已经在 Mac OS X 上安装了 GDB，为了测试它是否有效，我使用了以下 C 程序。

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[]) {

    int *my_array = (int *) malloc(5 * sizeof(int));
    int i;
    for (i = 0; i < 1000000; i++) {
        my_array[i] = i;
    }

    free(my_array);

    return 0;

}

我编译的时候出错，这是正常的(segmentation fault)

但是，当在编译命令中添加 -g 标志 并在我编译的程序上运行 gdb 时，我在启动命令run

后收到此消息

During startup program terminated with signal ?, Unknown signal.

真不知道是从哪里来的。我添加了一个证书以确保 gdb 在 OS X 上正常工作，但我没有发现任何可以解决此问题的方法。

This is how I easily fixed the issue. [Update: based on feedback received and yet to be verified, it seems that this solution works with macOS Sierra 10.12 but not with macOS Sierra 10.12.2]

See video instructions here

Quit gdb

Using your text editor e.g. Sublime Text, save a file called “.gdbinit” [Exclude the quotation marks] in your user folder.

In the file add the following: “set startup-with-shell off” [Exclude the quotation marks]

Save the file

gdb should now work

.gdbinit 位于何处，我该如何编辑它？
