[Mono-devel-list] [mono 1.0.2] nested class property gives Segmentation fault

Causes infinite recursion and a stack overflow, since Number = value
calls the 'set' method
of the property. To  solve this, define an instance variable to hold
the value of the property:

private string number;

public string Number {
        get {
              return number;
         }
         set {
              number = value;
         }
}

Mono can't currently handle stack overflow very well.
