#785: scipy.spatial problem for 64 bits python2.4
--------------------+-------------------------------------------------------
 Reporter:  cdavid  |       Owner:  peridot

 Severity:  normal  |    Keywords:         
--------------------+-------------------------------------------------------
 Several scipy.spatial tests fail on 64 bits arch under python 2.4 (this is
 different from the other problem reported in #779):

 }}

 I am not sure, but I believe Py_ssize_t is an int in python 2.4, even on
 64 bits arch (whereas Py_intrptr_t is just an alias to intptr_t, that is
 has to be 8 bytes to 64 bits arch), which would explain the problem. I
 don't know if that's a cython problem or scipy.spatial.
