(12.2.5)
The temporary to which the reference is bound or the temporary that
is the complete object of a subobject to which the reference is bound
persists for the lifetime of the reference except as specified below.
...略
In all these cases, the temporaries created during the evaluation of
the expression initializing the reference, except the temporary to
which the reference is bound, are destroyed at the end of the full
-expression in which they are created and in the reverse order of the
completion of their construction.
