Hi

with the latest svn versions I get:

##########################################################################################
scipy.test(verbostiy=2)

[...]

##########################################################################################

The test runs fine and crashes when the hankel1 function is called.

Calls to the other hankel function (defined in the _cephes module) also 
end up in float exceptions:

scipy.special._cephes.hankel1(1,1)
scipy.special._cephes.hankel1e(1,1)
scipy.special._cephes.hankel2(1,1)
scipy.special._cephes.hankel2e(1,1)

Outcommenting the tests of these functions in 
special/tests/test_basic.py makes place for more exceptions when calling 
other functions (i0e, i1e, ive, jve, k0, and probably many more), all 
from the _cephes module.

Any ideas?

cheers,
steve

Should array indices start at 0 or 1? My compromise of 0.5 was rejected 
without, I thought, proper consideration.
