Depending on the allocator, existing code leaks memory.

I have no idea how Coverity tracks these things but is this maybe the reason for https://github.com/ofrobots/node/blob/59a012aeb976347d6975c82fb376b5db41da146c/src/node_perf.cc#L217 ?

Also, out of curiousity, on which systems was this noticeable?

@addaleax At Google we use sized deletes, which caught this once we upgraded to 8 LTS.

The coverity comment you point you to is possibly related to this, but /cc @bnoordhuis in case there was another reason to add it.

Not the same thing. leaked_storage is for when Coverity can't track where a heap allocation is freed.
