Lion's libc++ headers do not support shared_ptr under -fno-rtti. This is <rdar://problem/10217868>. Apparently I'm using Lion's libc++ headers somehow, which I should probably fix; but since the use of shared_ptr is just a hack until DenseMap supports move-only types, I don't feel bad about changing it to a different hack that avoids shared_map altogether.
