Running the test by hand I get:

octave:3> test quadgk
***** assert (quadgk (@(z) log (z),1+1i,1+1i, "WayPoints", [1-1i, -1,-1i,
-1+1i]), -pi * 1i, 1e-6)
!!!!! test failed
max_recursion_depth exceeded

this is only on i686.

It appears that with:

a =  1 + 1i
b =  1 + 1i

b < a is evaluating to true.

octave:4> a =  1 + 1i
a =  1 + 1i
octave:5> b =  1 + 1i
b =  1 + 1i
octave:6> b < a
ans =  1
octave:7> b > a
ans = 0
octave:8> b == a
ans =  1

Any idea where to look next?
