Il comportamento è indefinito se uno dei valori in v viene calcolato durante l'assegnazione e dipende qualsiasi dei valori in *this, cioè, l'espressione sul lato destro della cessione si riferisce ad una variabile nel lato sinistro della assegnazione.

Original:

The behavior is undefined if any of the values in v is computed during the assignment and depends on any of the values in *this, that is, the expression on the right side of the assignment refers to a variable in the left side of the assignment.
