           Summary: Internal error: backend\cgobj.c 2313 with
                    Rebindable!(immutable TimeZone) in std.datetime
           Product: D
           Version: D2
          Hardware: All
                OS: Windows

         Component: DMD

If I change line# 8960 in std.datetime.SysTime

    Rebindable!(immutable TimeZone) _timezone;

to

    Rebindable!(immutable TimeZone) _timezone = UTC();

then on 32-bit Windows, we get this wonderful error message

It compiles just fine on the other platforms, but it fails on 32-bit Windows
(64-bit Windows does not appear to currently be part of the autotester, so I
don't know how it fairs there). Given the fact that "backend/cgobj.c" has the
word backend in it, I assume that the bug is either in the glue layer with the
backend or in the backend itself, but I don't know. Regardless, this is
currently blocking

Unfortunately, I have been unable to reproduce this problem with a test case
separate from std.datetime, but it's very easy to reproduce with std.datetime.
