C++14 allows to merge and remove global allocations [expr.new]: "An implementation is allowed to omit a call to a replaceable global allocation function (21.6.2.1, 21.6.2.2). When it does so, the storage is instead provided by the implementation or provided by extending the allocation of another new-expression." Moreover, clang already does the elisions: https://godbolt.org/g/jPGuk6
