I have been experimenting with setjmp / longjmp under Windows as a way to break out of an endless loop. With my experiments, longjmp appears to silently exit the process, no stack trace, nothing. Black emptiness.
I don't think breaking out of a loop this way can work. The CtrlHandler is called by another thread. Quoting from https://docs.microsoft.com/en-us/windows/console/handlerroutine:
An application-defined function used with the SetConsoleCtrlHandler function. A console process uses this function to handle control signals received by the process. When the signal is received, the system creates a new thread in the process to execute the function.
