------------------------------------------------------------------
Hmm, so I tried to build protobuf 3.20.1 from source...
If I use the standard Ubuntu 20.04 build tools, the symbol is exported (see
uppercase "W") by the generated {{libprotobuf.so}}:
{code}
$ nm --demangle ./src/.libs/libprotobuf.so | rg ~InternalMetadata
00000000000f8e10 W
google::protobuf::internal::InternalMetadata::~InternalMetadata()
00000000000f8e10 W
google::protobuf::internal::InternalMetadata::~InternalMetadata()
{code}
However, if I use the conda-forge build tools, the symbol is local (see
lowercase "t"):
{code}
$ nm --demangle ./src/.libs/libprotobuf.so | rg ~InternalMetadata
00000000000c3870 t
google::protobuf::internal::InternalMetadata::~InternalMetadata()
00000000000c3870 t
google::protobuf::internal::InternalMetadata::~InternalMetadata()
{code}
