Hi, I just built 3.8.0 on Ubuntu 12.04 64bit (all standard config options), and one of the svds checks fails:
***** testif HAVE_ARPACK, HAVE_UMFPACK [u2,s2,v2,flag] = svds (A,k,0,opts); s2 = diag (s2); assert (flag, !1); tol = 10 * eps() * norm(s2, 1); assert (s2, s(k:-1:1), tol); warning: returning fewer singular values than requested warning: try increasing the value of sigma !!!!! test failed ASSERT errors for: assert (,) Location | Observed | Expected | Reason . O(6x1) E(7x1) Dimensions don't match

%! rand ("state", 42); > Markus Marco
