My code is almost identical to the basic C++ tutorial <https://grpc.io/docs/languages/cpp/basics/>, but for server side streaming, not client, and calling the blocking/synchronous versions, not the Async versions. The exception (below) is occurring in ClientReader::Read(). Initially, the size of ClientRpcInfo.interceptors_ is 0. However, in client_context.h, line 481, the entire rpc_info_ object is overwritten, and at that point the size becomes 3952075555, obviously incorrect. At this point, the logic ends up in the grpc::experimental::ClientRpcInfo::RunInterceptor() and with incorrect data generates an "Exception 0xc0000005 encountered at address 0x7ff7dd2f5961: Access violation reading location 0xffffffffffffffff".
I have reread the tutorial several times, and do not think I am missing any steps. I create a channel, then the stub, then connect to the server. That and a non-streaming call works, but reading from the stream on the client dies. What might I be doing wrong? The gRPC version being used is pulled in using vcpkg under Windows. What is might be missing? Also, I do not need any experimental features, but have not found a way to exclude that code.
