           Summary: writefln() on an associative array fails hard
           Product: D
           Version: 1.00
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: deewiant at gmail.com


import std.stdio;

void main() {
        int[int] foo;

        foo[1] = 2;

        writefln("%s", foo);
}

This outputs "[", some seemingly-random numbers including hundreds of zeroes,
and dies in an Access Violation. It looks like it's reading memory in the
completely wrong place, possibly treating the AA as a dynamic array.
