735. Missing case in specification of safely-derived pointers

[Voted into WP at October, 2009 meeting.]

The bullets in _N4885_6.7.5.5.4 [basic.stc.dynamic.safety] paragraph 2 do not appear to cover the following example:

   int& i = *new int(5);

   delete &i;

Should &i be a safely-derived pointer value?

Proposed resolution (September, 2009):

Change _N4885_6.7.5.5.4 [basic.stc.dynamic.safety] paragraph 2, bullet 2, as follows:
