quadl.m test fail

[Andreas Weber]

Hello list,

one test in quadl fails since more than 3 weeks (I guess since the first
code sprint).

octave:2> test quadl
  ***** assert ( quadl (@(x) sin (2 + 3*x).^2, 0, 10, 0.3, []),
        (60 + sin(4) - sin(64))/12, -0.3)
!!!!! test failed
assert (quadl (@(x) sin (2 + 3 * x) .^ 2, 0, 10, 0.3, []),(60 + sin (4)
- sin (64)) / 12,-0.3) expected
 4.8603
but got
 8.1963
maximum relative error 0.686392 exceeds tolerance 0.3

Jordi told me in #octave that he is aware of that so perhaps it should
be marked as "expected failure" until the problem is fixed?
