Here's my code in main function:
```
     auto fiber = new Fiber({
         while (true) {
             Thread.sleep(1.seconds);
             Fiber.yield;
         }
     });

     void foo() {
         while (true) {
             fiber.call;
             //Thread.sleep(1.seconds);
             //"---".writeln;
         }
     }

     new Thread({
         foo();
     }).start;

     new Thread({
         Thread.sleep(500.msecs);
         foo();
     }).start;

```
If I comment the `fiber.call;`, all works.

Fibers in D are not meant to be run in multiple threads.
