<pre>This is the implementation of std::allocator<T>::deallocate from
<a href="http://llvm.org/svn/llvm-project/libcxx/trunk/include/memory">http://llvm.org/svn/llvm-project/libcxx/trunk/include/memory</a> :
_LIBCPP_INLINE_VISIBILITY void deallocate(pointer __p, size_type) _NOEXCEPT
{_VSTD::__deallocate((void*)__p);}
This is suboptimal for toolchains that implement an optimized sized-delete
(that is, ::operator delete(void *ptr, size_t s).)
I think this should invoke
_VSTD::__deallocate((void *)__p, size * sizeof(T))
or something similar (with the obvious implementation of sized __deallocate.)</pre>
