The default allocator for the standard library (STL) stuff is implementation dependent. That means it won't necessarily use the same memory pool as operator new. Moreover, even within any given pool, depending on the implementation, the implementor might decide to allocate memory for different scenarios.
You'd probably have reasonable luck allocating/deleting/allocating/deleting with operator new and/or the stl's allocator, but not necessarily when you mix the two.
But my problem now is that in some application I'm creating a 'temporary' std::multimap which takes about 500MB. But now I want to make sure the application is going to reuse this memory later during the lifetime of the app (but not necessarily for stl objects) because otherwise it might run out of memory.
