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 ?

I just realized there was more before The question I answered. The bug got
fixed in versi?n 4.5.0 of gcc, thus it is unsupported to build with earlier
versions. The message seen is an instance of this bug.

Then we also have a problem with the host variant: host-protobuf also
requires gcc >= 4.5.0. I've restarted my autobuilder, and it uses an
old version of gcc on the host, which causes host-protobuf to fail
building:

I'll give it a shot at reproducing locally. Hopefully I can patch the
triggering instances.
If I succeed, I'll commit a different patch to support building on
older versions of gcc,
and will send it upstream, too, so the patches can be dropped in a
following version.
Wish me luck!

Another data point, This Ubuntu host GCC seems to not have the issue,
so some distros have pulled the fix in.
g++ (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4

Well, the problem has been fixed in gcc upstream since 4.5 apparently,
so obviously a 4.8 gcc does not exhibit the issue, and it's not because
of distro-specific patches.

I got gcc 4.3 to build on my Arch box, so I'll try to get it building with it.
I'll probably send the patches to work around this issue by the weekend.
Cheers,
Mario.
