compiling with GDC

[Numpsy]

I just tried building the test code from issue #16 with GDC-MingW (The gcc-4.6.1-tdm64-1-gdc-7e1a98da2769-20120428-D2.058 build from https://bitbucket.org/goshawk/gdc/downloads), and got the error:

orange\orange\serialization\Serializer.d: In member function 'getSerializedReference':
orange\orange\serialization\Serializer.d:1561:0: error: cannot convert to a pointer type
orange\orange\serialization\Serializer.d: In member function 'addSerializedReference':
orange\orange\serialization\Serializer.d:1522:0: error: cannot convert to a pointer type

Where T is A[string].

This compiles with DMD. So is this a problem with my code or GDC?

It looks like the issue is that

int[string] a;   
auto b = cast(void*) a;

compiles with DMD, but fails with

  error: cannot convert to a pointer type

on GDC.
I don't know if this is supposed to work or not.
