[Bug libstdc++/13624] New: Unsafe delimiter in ostream_iterator

["jlquinn at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

An ostream_iterator constructed with a stream delimiter will break if the string
is destroyed since the class just stores a pointer to the constructor argument.
 I.e.

char *x = new char[4];
strcpy(x, "ugh");
ostream_iterator<int> it(cout, x);
delete[] x;
*it = 5;

A copy needs to be made for safety.  Present in 3.2, 3.3 as well.
