How to send a signal to a process to cause call to exit() and terminate

Question

I have a program that only generates the output when it returns normally or when it calls the exit() function (I'm trying to use gcov on a C program). On a special input my program hangs in an infinite loop so I have to terminate it by sending termination signal. In this situation it won't produce the output I need since it wouldn't call exit() .

Is there any way that I can force a running program to call exit() and terminate without touching the source code and writing a signal handler?

正如评论中所建议的那样，我在gdb执行了我的程序，并在收到信号后手动调用exit() ，它的工作方式就像魅力。
