Using the current Maxima + CCL, rtest_eigen (in the share testsuite) doesn't finish. The problem seems to be
similaritytransform(matrix ([3, 2, 1, -5], [-1, 2, 1, -3], [5, -1, 2, 4], [3, 1, -1, 5]));
This is part of the last test in rtest_eigen. The test suite (non share test suite) runs OK for me. Maybe somebody
can verify that this is a new bug.
