* v8::internal::GlobalBackingStoreRegistry::Register(std::shared_ptr<v8::internal::BackingStore>)
* v8::ArrayBuffer::GetBackingStore()

* zmq::Socket::Receive(Napi::CallbackInfo const&) 

Describe the bug
Crash in zmq::IncomingMsg::IntoBuffer(Napi::Env const&) when using zero-copy. The address of the buffer used by a zmq_msg_t buffer is not unique, which appears to be incompatible with the way the new v8 BackingStore api.. The underlying zmq_msg_t uses reference counting to implement shallow copying behavior and it may return the same address for multiple messages

Reproducing
I tried to run the unit tests and I ran into this issue. It seemed to fail when it hit "should release buffers" failed in "socket-send-receive-test.ts"

Expected behavior
No crash.
