gdb 显示在启动过程中程序正常退出。在 WSL 中（Windows 上的 Bash，Linux 的 Windows 子系统）

Question

我正在使用 WSL（Windows 上的 Bash = Linux 的 Windows 子系统）。 我写了一个简单的代码，a.c

#include <stdio.h>

int main(int argc, char *argv[]) {
    printf("Hello\n");
    return 0;
}

我编译了。

$ gcc -g -o a.exe a.c
$

效果很好。

$ ./a.exe 
Hello
$

而且，我尝试在 gdb 中执行 a.exe。但是，我得到“在启动过程中程序正常退出。”

$ gdb ./a.exe

看起来这已经被报告并修复了WSL bug。

作为一种解决方法，您可以在调试之前set disable-randomization off，请参阅https://github.com/Microsoft/WSL/issues/2870#issuecomment-359664608。或者将 WSL 更新到最新版本。
