This bug is marked as FIXED, and it has been fixed since many years.

What is the actual problem you are seeing? Is there a reference to an
autobuilder issue?

I've tried to build with gcc 4.3, and indeed I'm getting:

./google/protobuf/metadata.h: In constructor 'google::protobuf::internal::InternalMetadataWithArena::InternalMetadataWithArena(google::protobuf::Arena*)':
./google/protobuf/metadata.h:175: error: class 'google::protobuf::internal::InternalMetadataWithArena' does not have any field named 'InternalMetadataWithArenaBase'
./google/protobuf/metadata.h: In constructor 'google::protobuf::internal::InternalMetadataWithArenaLite::InternalMetadataWithArenaLite(google::protobuf::Arena*)':
./google/protobuf/metadata.h:204: error: class 'google::protobuf::internal::InternalMetadataWithArenaLite' does not have any field named 'InternalMetadataWithArenaBase'

Is this the issue we're talking about ?
