Another test case that doesn't work properly:
////////////// Digital Mars D Compiler v1.009 // libphobos ///////
 import std.stdio;
 void main() 
 {
         int[char] x;         // Visually: = ['a':1, 'b':2] // associative
array
         x['b'] = 123;
         writefln(x);  // this prints out: [b:2063597568]
         writefln(x['b']); // this prints out: 123
 }
////////////

Also, there was this comment by Frits van Bommel on the mailing list at

Looks like it's (the value that gets inserted) << 24, or in other words 
the lower byte is put in the high byte, and the others are cleared.
It looks like it's dependent on the key size: if the key type is changed 
to ushort the upper two bytes are filled with what should be the lower 
two bytes, and if it's a three-byte struct (with toString) the upper 
three bytes should be the lower three bytes and the lower byte seems to 
be garbage.

This bug doesn't seem to affect GDC.
It looks like gphobos' std.format.doFormat.formatArg.putAArray was 
patched to make sure access to AA internals is performed on the correct 
alignment boundary. This may have been done for portability reasons, but 
I'm guessing it also fixes this bug.
Would anyone mind confirming this and submitting a bug + patch to bugzilla?
