Under Windows, using foreach to iterate over an uninitalized AA generates an
Access Violation.

import std.stdio;

void main(){
        uint[char[]] foobar;
        foreach(value; foobar){} // fails on foreach
}

I experimented with this a bit after it broke a bit of SDWF.  It happens only
if the AA is actually uninitialised - if you've added something to the AA and
then deleted it then it behaves correctly.

It's a bug I introduced when fixing other problems in the AA. It's fixed 
now, and will go out in the next update.
