#11879: Incorrect use of reset cause unexpected impact on previous code segment
-----------------------+------------------------------
 Reporter:  anonymous  |       Type:  Bugs
   Status:  new        |  Milestone:  To Be Determined
Component:  None       |    Version:  Boost 1.61.0
 Severity:  Problem    |   Keywords:
-----------------------+------------------------------
 #include <boost/scoped_ptr.hpp>
 #include <iostream>

 int main()
 {
   boost::scoped_ptr<int> p{new int{1}};
   std::cout << *p << '\n';
   std::cout << p.get() << '\n';
   p.reset(new int{2});
   std::cout << *p.get() << '\n';
   std::cout << p.get() << '\n';

   p.reset((int *)4); //Problem: Because of this statement std::cout of
 above lines are not printing anything. When this line is commented the
 program works fine. I understand I have used reset function incorrectly
 but it should impact to the next statements but it is also impacting above
 statements too. Please explain the cause.

   std::cout << *p.get() << '\n';
   std::cout << p.get() << '\n';

   p.reset();
   std::cout << std::boolalpha << static_cast<bool>(p) << '\n';
 }
