This assumes that ix does not change during erase()
and so that the range is the same.  This form is
inherently problematic.  So, lets try a better form for the
problem.

        class X x;
        for ( X::iterator ix=x.begin(); ix != x.end(); ix.erase() );

where ix.erase() changes ix to continue to "point to" a
valid value or to x.end() when none are left.

How about this case?

Good Day
