Simplifying the input to integrate makes the bug disappear.
The denominator is sqrt(cos(4*z)+3)/2.
So it may be a bug, but perhaps a bug in the simplifier, not the
integrator. A
better bug reporter would distinguish the two cases. Perhaps an
automated bug
reporter is too unsophisticated to provide such information.
