This isn't actually a regression. It fails on D2.00, and D1.020, 1.041, 1.055
as well. 

Reduced test case:
---------------
struct Foo
{
    int x;
}

Foo getFoo(Foo irrelevant)
{
    Foo p = Foo(400);
    if ( p.x > p.x )
        return irrelevant;
    else
        return p;        
}

void main()
{
   assert(getFoo( Foo(0) ).x == 400);
}
