How to do it...

Fixing it is very simple; we need only to replace the pointer with offset_ptr<>:

#include <boost/interprocess/offset_ptr.hpp> struct correct_struct { 
    boost::interprocess::offset_ptr<int> pointer_; 
    // ... 
    int value_holder_; 
}; 

Now, we are free to use it like a usual pointer:

int main() {    boost::interprocess::managed_shared_memory         segment(boost::interprocess::open_or_create, "segment", 4096);    correct_struct* ptr =        segment.find<correct_struct>("structure").first;    if (ptr) {        std::cout << "Structure found\n";        assert(*ptr->pointer_ == ethalon_value);        segment.destroy<correct_struct>("structure");    }}
