Custom allocator for shared_ptr
Hello all, I assume that the reference count object pointed to by shared_ptr objects is on the heap. Is there a way that I can specify a custom allocator for shared_ptr to use for this purpose? Thanks, Dave

No, sorry. But if you grep for BOOST_SP_USE_STD_ALLOCATOR, you'll see where to patch your local copy - it should be easy. Out of curiosity, why do you need to use a custom allocator? To find leaks, for performance reasons, or because of tight memory requirements (embedded systems)?

boost pool allocators would be a great example. They are really useful, and it's a pity that I cannot use them with shared_ptr. Andrey

To be honest, I'm quite surprised it cant be used an allocator with shared_ptr. Is there any reason it cant?
