Hmm the library publishes a load of symbols that seem unnecessary at
best:
$ readelf -Ws /usr/local/lib/libprotobuf-lite.so | grep -v " UND " | grep -v
6google8protobuf | wc -l
123
2.6.1 seems far more reasonable:
$ readelf -Ws /usr/lib/x86_64-linux-gnu/libprotobuf-lite.so.9 | grep -v " UND "
| grep -v 6google8protobuf | wc -l
10
I'm especially suspicious of the following leading to entanglement with
libstdc++:
$ readelf -Ws /usr/local/lib/libprotobuf-lite.so.10 | grep -v " UND " | grep -v
6google8protobuf | grep _ZNS
