Niels Lohmann 2038838eea Copy the diff frame's members instead of holding a reference to it ...

The loop in diff_iteratively held a reference to the top frame, which
enter() invalidates when it pushes and the end of the loop invalidates
when it pops. Nothing used it afterwards, but a later change could. As in
the other iterative walks, the members the loop reads are now copied out
as constants and the ones it advances are changed through stack.back().
The frame as a whole is not copied: it holds the common keys and the
"add" operations of an object.
