I could not reproduce this using either stock gawk 3.1.5 or the current CVS
sources.  I suggest that you try building from scratch from the CVS archive
on savannah.gnu.org.

For the empty line I get

        R=1 S=1 L=0

If building from scratch still causes a failure, please let me know.
Otherwise, please report it to the Ubuntu people.

Thanks,
