Я пытаюсь создать класс, управляющий вектором с общей памятью (std) строк.

typedef boost::interprocess::allocator shmem_allocator;
typedef boost::interprocess::vector shmem_vector;

shmem_mgr::shmem_mgr() :
    shmem_(create_only, SHMEM_KEY, SHMEM_SIZE),
    allocator_(shmem_.get_segment_manager())
{
    mutex_  = shmem_.find_or_construct(SHMEM_MUTEX)();
    condition_ = shmem_.find_or_construct(SHMEM_CONDITION)();
    //buffer_ is of type shmem_vector
    buffer_  = shmem_.construct(SHMEM_BUFFER_KEY)(allocator_);
}

void shmem_mgr::run() {
    running_ = true;

    while(running_) {
        scoped_lock lock ( *mutex_ );

        int size = buffer_->size();

        log_.debug() < size < " queued request(s) found" < std::endl; //LINE 27
        for(int i=0; i
