Temporary object deleted too late...

Question

#include <string>
#include <memory>
class A{
pubilc:
   const std::string& getId() const{ return i_id;}
private:
   const std::string i_id;
namespace{
std::auto_ptr<A>
return_autoptr_object(const char* arg)
  A* const ret = new A(/*arg*/);
  return std::auto_ptr<A>(ret);
int main()
    const std::string myID=return_autoptr_object("test_autoptr")->getId();
    typedef void end_of_block_scope;
    std::cout << "*** out of scope here ****" << std::endl;
  return 0;
}The code above shows that a temporary object(returned by return_autoptr_object(..)) is deleted only AFTER(?) "out of scope here" line being printed. I expected it should be deleted right after it's being assigned its' id to "myID", where the checkpoint for that function exists, and NOT when it goes out of scope (of the block).
I tested it with other two compilers(gcc and visual age c++), both yield to the same expected result, only sun CC had diff result.
Possibly it's a bug?

Just a quick remark: It is with sunstudio 12 that lifetimes become standard. SunStudio 11 still has the same old behavior.
#include <iostream>
struct testerClass
        testerClass() {}
        ~testerClass() {std::cout << "Destructor for testerClass" << std::endl;}
        void doit() {std::cout << "doit invoked" << std::endl;}
int main()
        testerClass().doit();
        std::cout << "Out of scope by now" << std::endl;
}a) /opt/SUNWspro/v11/bin/CC main.cc
doit invoked
Out of scope by now
Destructor for testerClass
b) /opt/SUNWspro/v11/bin/CC -features=tmplife main.cc
doit invoked
Destructor for testerClass
Out of scope by now
