Your best guess at this point is probably Valgrind. Recompile the etch version with debug information (remove the "dh_strip" line in debian/rules), then run mountd with "valgrind --leak-check=full rpc.mountd -F -d all". After it's started leaking, just Ctrl-C it and see what comes out. You're probably most interested in the "definitely leaked" part.
In attach the valgrind output with libc6-dbg installed and /etc/nsswitch configured to use files for netgroups instead of ldap. The memory leaks is still there.
