on 3..2.3-RC1 cygwin I had

  ***** testif HAVE_ARPACK
 [u2,s2,v2,flag] = svds(a,k,0);
 s2 = diag(s2);
 assert(flag,!1);
 assert(s(k:-1:1), s2, 1e-10); 
!!!!! test failed
assert (s (k:-1:1),s2,1e-10) expected
   38.034
   38.034
   38.015
   38.015
   38.004
   38.004
but got
   38.060
   38.034
   38.034
   38.015
   38.015
   38..004
   38.004
Dimensions don't match>>>>> 

Is eventually the expected value wrong ?
