Details:

Debian wheezy, libcholmod1.7.1

"make check" after build of b14cdae65abd (stable) reports for
dldfcn/chol.cc-tst

ASSERT errors for:  assert (cca' * cca,ca,16 * eps)
  Location  |  Observed  |  Expected  |  Reason
   (3,3)     16+5.5511e-17i       16        Abs err 3.5531e-15 exceeds tol

I can reproduce this on 2x AMD Phenom II X6 CPUs and 1x AMD Athlon(tm) 64 X2
