I am trying to use a vector with a managed_mapped_file. http://www.boost.org/doc/libs/1_35_0/doc/html/boost/interprocess/vector.html seems to indicate this can be done. When I try to run the code below, it fails with a "bus error" (on OS X) after printing "Entering item in vector".  What am I doing wrong? Also, how can I grow this managed_mapped_file as I add things to the vector? I get runtime errors using the managed_mapped_file::grow() function.

The code below should just fill up a vector with powers of 2, and print it. I am trying to understand the library before I implement it for something real.

Code below:

#include <boost/interprocess/file_mapping.hpp>
#include <boost/interprocess/mapped_region.hpp>
#include <boost/interprocess/containers/vector.hpp>
#include <boost/interprocess/managed_mapped_file.hpp>
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/containers/vector.hpp>
#include <boost/interprocess/allocators/allocator.hpp>
#include <iostream>
#include <fstream>
#include <cstring>
#include <cstddef>
#include <cstdio>   
#include <cmath>

int main ()
   using namespace boost::interprocess;
     std::cout << "Starting" << std::endl;
     managed_mapped_file mfile (open_or_create, "MyMappedFile", 65536);
     std::cout << "Mapped file" << std::endl;

     typedef allocator<int, managed_shared_memory::segment_manager> ShmemAllocator;
     typedef vector<int, ShmemAllocator> MyVector;
     const ShmemAllocator alloc_inst (mfile.get_segment_manager());

      std::cout << "Making vector" << std::endl;

      MyVector* vec = mfile.construct<MyVector>("vec")(alloc_inst);
      std::cout << "Made vector" << std::endl;
       std::cout << "Filling vector" << std::endl;
      int i = 0;
      for(i = 0; i < 63; ++i)
         std::cout << "Entering item in vector" << std::endl;
         std::cout << "Entered item in vector" << std::endl;
      std::cout << "Filled vector" << std::endl;
      std::cout << "Size of vec is:\t" << vec->size() << std::endl;
      std::cout << "Reverse printing contents of vector" << std::endl;
      for(i = vec->size()-1; i >= 0; --i)
         std::cout << "At " << i << ":\t" << vec->at(i) << std::endl;    
      std::cout << "Printed contents of vector" << std::endl;
   catch(interprocess_exception &ex){
      std::cout << ex.what() << std::endl;
      return 1;
   return 0;
