           Summary: this.outer in nested classes gives a bogus pointer
           Product: DGCC aka GDC
           Version: 0.24
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: wrong-code
          Severity: normal
          Priority: P2
         Component: glue layer
        AssignedTo: dvdfrdmn users.sf.net
        ReportedBy: jarrett.billingsley gmail.com


Have some code:

module foo;

import tango.io.Stdout;

abstract class Base
{
        void foo();
}

class A
{
        void print()
        {
                Stdout.formatln("I'm A!");
        }

        Base getBase()
        {
                return new class Base
                {
                        override void foo()
                        {
                                this.outer.print();
                        }
                };
        }
}

void main()
{
        auto a = new A();
        auto b = a.getBase();
        b.foo();
}


This causes a segmentation fault.  If you inspect this.outer, it's completely
bogus -- this.outer.classinfo is filled with garbage, etc.  This same code
works fine when compiled with DMD on Linux.
