This source file crashes the compiler for me:
--------------------------
struct Object{} 
class Game {} 
--------------------------
..using dmd2 / windows / VisualD / VS2010Int

Changing 'Object' to any other string makes the crash go away.
Removing the second line ("class Game {}") makes the crash go away.

The assert is:
Assertion failure: 'b->type->ty == Tclass' on line 449 in file 'class.c'

In 'class.c' in the src directory (C:\dmd\src), the assert appears to be on
line 446.
Function:
  void ClassDeclaration::semantic(Scope *sc)
Code:
// If no base class, and this is not an Object, use Object as base class
if (!baseClass && ident != Id::Object)
{
// BUG: what if Object is redefined in an inner scope?
Type *tbase = new TypeIdentifier(0, Id::Object);
BaseClass *b;
TypeClass *tc;
Type *bt;

if (!object)
{
    error("missing or corrupt object.d");
    fatal();
}
bt = tbase->semantic(loc, sc)->toBasetype();
b = new BaseClass(bt, PROTpublic);
baseclasses.shift(b);
assert(b->type->ty == Tclass); **** LINE 446 ****
tc = (TypeClass *)(b->type);
baseClass = tc->sym;
assert(!baseClass->isInterfaceDeclaration());
b->base = baseClass;
}
