Version 1.9.1: Failed to process proto source files

[Ismaxis]

I was generating REST API endpoin, using gRPC Gateway, by adding custom annotations, which requeired including some vendor .proto files, such as descriptor.proto. After adding annotations, I successfully generated .pb.gw.go files and calls to REST API worked just fine.

But calls to gRPC API, using grpcurl, stopped working:

Failed to process proto source files.: could not parse given files: google/protobuf/descriptor.proto:1070:5: extension range cannot have declarations and have verification of UNVERIFIED

Then I tried other versions of grpcurl and figured out that same calls wokred with versions from 1.8.2 to 1.8.9.

We have the same error since 1.9.0.
I can also confirm that it's still working with 1.8.9.
