The test is:

  arg = [1, 1; 0, 1];
  result = [2.718281828459045, 2.718281828459045;
            0.000000000000000, 2.718281828459045];
  all (all (abs (expm (arg) - result) < 2*eps))

My guess is it is not computing a result to the expected precision.

What is the max difference on your system?  If it is reasonably small
(say < 256*eps or so) then probably we should just increase the
tolerance in the test file.
