How are you identifying those as leaked ?
IIRC, exports are those symbols marked with 'T' in the nm
output:
[man nm]
· The symbol type. At least the following types are used;
others are, as well, depending on the object file format.
If lowercase, the symbol is usually local; if uppercase,
the symbol is global (external). There are however a few
lowercase symbols that are shown for special global
symbols ("u", "v" and "w").
"T"
"t" The symbol is in the text (code) section.
[/man]
# nm -a .libs/libvirt-admin.so | grep ' T '
0000000000001c80 T virAdmConnectClose
00000000000017d0 T virAdmConnectOpen
0000000000001d30 T virAdmConnectRef
# nm -a .libs/libvirt-admin.so | grep virAdmConnectNew
00000000000037c0 t virAdmConnectNew
So, IIUC, that lowercase 't' means the symol is local, and
exported.
