我正在Visual Studio下调试此代码（不是Visual Studio代码）：

#include <cstdio>
#include <signal.h>
#include <unistd.h>

int n = 0;

void handleSignal(int sig) {
//it works from terminal but not from IDE
    printf("Signal received: %d - %d times\n", sig ,++n);
}

int main()
{
    printf("Hi From WSL! - PID: %d\n", getpid());
    auto s = signal(SIGUSR1, handleSignal);

    printf("signal was %d\n", s); // prints 0

    while (n<10) {
        printf("sleeping - %d\n", n);
        sleep(1);    
    }
    printf("Received signals %d timeskill , exiting\n", n);
    return 0;
}

字符串
我跑

kill -10 <pid of process>

如果我从bash运行代码，一切正常

# output if run from bash:
$ ./LinuxConsoleApplicationWsl.out

(do printfs and at 10th signal sent the app exits）但是如果我从visual studio运行它，我得到了这个未处理的异常：

我错过了什么？
