Hello,

Please can somebody help me on this code (from boost site). I try to run it but I still get the following error:

/cygdrive/C/Program Files/NetBeans 7.1.2/ide/bin/nativeexecution/dorun.sh: line
33: 12900 Segmentation fault      (core dumped) sh "${SHFILE}"
Press [Enter] to close the terminal ...

This is the code for creating vector in shared memory:

#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/containers/vector.hpp>
#include <boost/interprocess/allocators/allocator.hpp>
#include <string>
#include <cstdlib> //std::system

using namespace boost::interprocess;

//Define an STL compatible allocator of ints that allocates from the managed_shared_memory.
//This allocator will allow placing containers in the segment
typedef allocator<int, managed_shared_memory::segment_manager> ShmemAllocator;

//Alias a vector that uses the previous STL-like allocator so that allocates
//its values from the segment
typedef vector<int, ShmemAllocator> MyVector;

//Main function. For parent process argc == 1, for child process argc == 2
int main(int argc, char *argv[])
{
   if(argc == 1){ //Parent process
      //Remove shared memory on construction and destruction
      struct shm_remove
      {
         shm_remove() { shared_memory_object::remove("MySharedMemory"); }
         ~shm_remove(){ shared_memory_object::remove("MySharedMemory"); }
      } remover;

      //Create a new segment with given name and size
      managed_shared_memory segment(create_only, "MySharedMemory", 65536);

      //Initialize shared memory STL-compatible allocator
      const ShmemAllocator alloc_inst (segment.get_segment_manager());

      //Construct a vector named "MyVector" in shared memory with argument alloc_inst
      MyVector *myvector = segment.construct<MyVector>("MyVector")(alloc_inst);
    ;


   }
   else{
       // some code
   }

   return 0;
};

I got an error for this instruction: MyVector *myvector = segment.construct<MyVector>("MyVector")(alloc_inst);
This addition information about the environnment: NetBeans 7.1.2 with Cygwin_4.x, gcc-core   3.4.4-999,
gcc-g++ 3.4.4-999,gcc-mingw-core        20050522-3,gcc-mingw-g++         20050522-3 ,gcc4-core             4.5.3-3 ,
gcc4-g++   4.5.3-3 , gdb 7.5.50-1. I am using Windows XP SP3.

Many thanks.
