I’ve been working on a c++ project utilizing Google protobuf<\/a>, and at one point ran into an error during application startup (static initialization):<\/p>\n libprotobuf ERROR google\/protobuf\/descriptor_database.cc:314] Invalid file descriptor data passed to EncodedDescriptorDatabase::Add(). <\/p>\n I came across two bug<\/a> reports<\/a> against protobuf that experienced this same error, but they seemed to be related to charset conversions. (This was briefly a red herring for me, since I had<\/em> run into a charset issue earlier the same day, but didn’t end up solving my problem.)<\/p>\n Stepping through the code with a debugger alerted me to where in the code the abort signal was being thrown: from a call to ::google::protobuf::DescriptorPool::InternalAddGeneratedFile(…) with a big hard-coded string inside the pb.cc (protobuf-generated) file. This was my After see that filename and remember the change I’d made, I just re-ran protoc ––cpp-out=.\/ <message.proto><\/span>, recompiled, and voilà, I was able to run without error!
