[SciPy-User] nan handling by scipy.optimize

Has there been any recent change in nan handling in scipy.optimize?
I'm using a very recent EPD distribution, and a student
is using a release with Python 2.6.5.  I'm getting a
zero returned by brentq and bisect when (iiuc) the function
evaluation produces a nan, while he is not.
The search interval is bounded away from zero.

Thanks for any insight,
Alan Isaac
