           Summary: Crash on overriding class methods with 'auto' return
                    type
           Product: D
           Version: 2.031
          Platform: Other
        OS/Version: All
            Status: NEW
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: jarrett.billingsley gmail.com


class A
{
    auto foo() { return 0; }
}

class B : A
{
    override auto foo() { return 5; } 
}


The compiler crashes.  It also crashes if A.foo's return type is int or B.foo's
return type is int (but not if both are int, obviously).  It doesn't crash if
foo is not overridden.

Is it the same as bug#3042?

With my patch for bug #3042 applied, this generates:

bug.d(4): Error: function ice.B.foo of type () overrides but is not covariant w
ith ice.A.foo of type ()

So marking as duplicate.

*** This issue has been marked as a duplicate of issue 3042 ***
