return string from inside if block => Segmentation Fault: 11

[Robert M. Münch via Digitalmars-d-learn]

I'm a bit confused... I have the following class:

class foo : superFoo {
 aFoo spec;
 aFoo lvars;
 aFoo bdy;

  override string toString(){
    if(spec.isEmpty() && lvars.isEmpty()){
      return "does spec";
    }

    if(lvars.isEmpty()){
      return "funct spec";
    }

    return "function spec";
  }
}

The thing is, as soon as one if the IFs is true and the return 
statement is executed I get a seg-fault: 11

If I comment the IFs it works. But I can't see any differences in 
returning from inside the if vs. the return at the end of the function.

Any idea?
