Looks like some sort of optimization for value of local variable - changing to a field make it terminate ok (note that volatile or correct locking should be used in actual code):

using System;
using System.Threading;

class Program
{
    static bool stop = false;
    static void Main(string[] args)
    {

        new Thread(() =>
        {
            Thread.Sleep(1000);
            stop = true;
            Console.WriteLine("Set \"stop\" to true.");

        }).Start();

        Console.WriteLine("Entering loop.");

        while (!stop)
        {
        }

        Console.WriteLine("Done.");
    }
}
