Garbage Collection Pitfall in C++ but not in D?

[akaz]

Hi,

 Reading about the C++11, I stumbled upon this:

 http://www2.research.att.com/~bs/C++0xFAQ.html#gc-abi

 Specifically (quote):

        int* p = new int;
        p+=10;
        // ... collector may run here ...
        p-=10;
        *p = 10;        // can we be sure that the int is still there?

 How does the D garbage collector solves (answers) that?

Thank you.
