Sorry, I wasn't reading your post correctly. I was referring to
open_shared_object.

For me, the following stripped down example throws already:

#include <boost/interprocess/managed_shared_memory.hpp>
using namespace boost::interprocess;
int main (int argc, char *argv[])
{
  managed_shared_memory segment(open_or_create, "MySharedMemory", 999999999);
}

$ ./a.out
terminate called after throwing an instance of
'boost::interprocess::interprocess_exception'
  what():
Aborted

This is due to an illegal size for the shared memory area on my
plattform (linux):

$ cat /proc/sys/kernel/shmmax
33554432

Shouldn't the exception report "invalid argument" if size > SHMMAX?

manish4gupta, what system are you running the example on?
