I guess this error can then be safely ignored.
I've uploaded a Slackware binary package for 5.14.0.

Dear all,
In my environment of CMUCL 19D on Mac OS X 10.5.1 on PPC,
test seems OK, as shown below.
In addition to the following log, as I reported in different email,
entire
src testsuite passes for CMUCL 19D on the same machine.
Maxima 5.13.99rc2 http://maxima.sourceforge.net
Using Lisp CMU Common Lisp Stage 3 20071108T014921 (19D)
Distributed under the GNU Public License. See the file COPYING.
Dedicated to the memory of William Schelter.
The function bug_report() provides bug reporting information.
(%i1) is (errcatch (rat (x^(2^128))) = []);
(%o1) false
I think releasing 5.14.0 now is a good decision.
