> transport_produce attempts to allocate a negatively sized buffer
> As soon as remote_max_frame is set, the code in transport_produce attempts to increase its buffer immediately up to that size when its initial size isn't enough. This causes a huge malloc to occur if the remote max frame size is large and also potentially overflows MAX_INT
