Fix unsafe memory access
The following expression
m[i] = m[j]
where m is a DenseMap and i != j is not safe. m[j] returns a
reference, which would be invalidated when a rehashing occurs.
If rehashing occurs to make room for m[i], m[j] becomes
invalid, and that invalid reference would be used as the RHS
value of the expression.
