Crash on RpcMethod constructor

[armstr...@gmail.com]

Im running OS X 10.15.3 with grpc installed via homebrew which gives grpc version v1.2.6 and protofub v3.11.2 

RpcMethod(const char* name, RpcType type,

            const std::shared_ptr<ChannelInterface>& channel)

      : name_(name),

        method_type_(type),

        channel_tag_(channel->RegisterMethod(name)) {}

and "channel->RegisterMethod" is an invalid address of 0x0

If I roll back protobuf to version 3.8.0 it works as expected.

Anyone seen this before?

Unfortunately grpc version 1.2.6 is probably too old for us to support (it was released almost 3 years ago). Please use a newer version of grpc.
