LLDB Debugger Never Ends in QtCreator

I am trying to use Qt Creator 3.5.1 to debug a piece of software that I wrote. I noticed that while debugging my program would just stop at random points, and I accepted these problems for threading issues. However, in the end, I found out that even when I run the simplest of programs, the debugger will continue to work forever, not ending.

I work on Mac (El Capitan) with Qt 5.5.1 and Xcode 7.3.

This is my very simple test program:

#include <iostream>
int main(int argc, char *argv[])
{
    std::cout << "Howdy, this is a simple test program." << std::endl;
    return 0;
}

When I run this in debug mode in Qt Creator without setting any breakpoints, it just doesn't end:

Debugging starts
Howdy, this is a simple test program.

Only when I press the button stopseveral times when the debugger returns to me withDebugging has finished
