POCleanup shared memory with vector inside

copied!<p>I'm using <strong>boost::interprocess::managed_shared_memory</strong> to share some data between different processes and was wondering how cleanup works. In general, I have to following situation:</p> <pre><code>boost::interprocess::managed_shared_memory *sharedSegment; typedef boost::interprocess::allocator< MyObject, boost::interprocess::managed_shared_memory::segment_manager> SharedMemoryAlloc; typedef boost::interprocess::vector<MyObject, SharedMemoryAlloc> SharedVector; SharedVector *sVec; unsigned int size; // Do some other stuff and determine correct size sharedSegment= new boost::interprocess::managed_shared_memory(boost::interprocess::create_only, "TEST", size); SharedMemoryAlloc *allocToSharedSegment = new SharedMemoryAlloc(sharedSegment->get_segment_manager()); sVec = sharedSegment->construct<SharedVector>("MyVector")( (*allocToSharedSegment) ); delete allocToSharedSegment; // Fill sVec, do some computation etc.. // Start cleanup //sVec->clear(); delete sharedSegment; boost::interprocess::shared_memory_object::remove("TEST"); </code></pre> <p>Since I call boost::interprocess::shared_memory_object::remove("TEST"); I always thought, that everything inside the memory is deleted anyway, and therefore I do not have to take care of sVec. But Visual Leak Detector told me, there were some memory leaks at this point. If I clear the vector before deleting the shared memory, everything works fine. Could it be, that sVec holds pointer internally and therefore I have to call clear()?</p>
