[dmd 2.066-b1] std.range.array with shared objects and AA rehash

[NCrashed via Digitalmars-d-learn]

I am using ranges (wrapped in InputRangeObject for use in 
interfaces) of shared objects, with new beta some cases are 
broken:
```
import std.range;

class A {}
InputRange!(shared A) foo()
{
        return [new A].inputRangeObject;
}

void bar()
{
        auto res = foo.array;
}

void main() {}
```
Fails with:
```
source/app.d(7): Error: cannot implicitly convert expression 
(inputRangeObject([new A])) of type 
std.range.InputRangeObject!(A[]).InputRangeObject to 
std.range.InputRange!(shared(A)).InputRange
/usr/include/dmd/phobos/std/conv.d(3914): Error: cannot 
implicitly convert expression (arg) of type shared(A) to app.A
/usr/include/dmd/phobos/std/array.d(2476): Error: template 
instance std.conv.emplaceRef!(shared(A)).emplaceRef!(shared(A)) 
error instantiating
/usr/include/dmd/phobos/std/array.d(64):        instantiated from 
here: put!(shared(A))
source/app.d(12):        instantiated from here: 
array!(InputRange!(shared(A)))
```

And also AA starts behave strange in shared context:
```
shared string[][string] map;

void main()
{
        map.rehash;
}
```
My AA is stored in shared class, the shared is inferred 
implicitly. Also following workaround works:
```
void main()
{
        (cast(shared(string[])[string])map).rehash;
}
```

Is this behavior a bug, or it works as expected?
