1.

src/usr.bin/showmount/showmount.c:335]: (error) Memory leak: ep

       if (!xdr_string(xdrsp, &strp, RPCMNT_PATHLEN))
            return (0);

2.

src/usr.bin/showmount/showmount.c:344]: (error) Memory leak: gp

          if (!xdr_string(xdrsp, &strp, RPCMNT_NAMELEN))
                return (0);

However, a close examination of the function xdr_exports shows
many places where a return is made in the middle of the function,
without any calls to free.
