Details:

On the current development source (changeset 13960:ef96344a6e58), the test for
quadl.m
  scripts\general\quadl.m ................................ PASS    4/5    FAIL
1


octave:1> test quadl
  ***** assert (quadl (@(x) sin (3*x).*cosh (x).*sinh (x),10,15),
         2.588424538641647e+10, -9e-15)
!!!!! test failed
assert (quadl (@(x) sin (3 * x) .* cosh (x) .* sinh (x), 10,
15),2.588424538641647e+10,-9e-15) expected
2.5884e+010
but got
2.5884e+010
maximum relative error 1.04636e-014 exceeds tolerance 9e-015



octave:3> format long
octave:6> (quadl (@(x) sin (3 * x) .* cosh (x) .* sinh (x), 10,
15)-2.588424538641647e+10)/2.588424538641647e+10
ans = -1.04636431086188e-014


If the relative tolerance become a little bit loose, this error will be
disappeared.

I propose that the tolerance value '-9e-15' is changed to '-1.1e-14'.
