[SciPy-Dev] cephes_smirnov never returns on mips/sparc/...

[Yaroslav Halchenko]

I have reported this issue some time ago on Debian
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=653948
and then forgot about it until now that I ran into it again.

With recent scipy (including git master 0fbfdbc)

scipy.stats.ksone.fit

seems to stall (never return) on big-endian boxes and return (1.0, nan,
nan) on x86.  It seems that it is  working correctly with scipy
0.7.2 (as it is now in Debian stable).

So -- is that anything known?

snippet to replicate:

import numpy as np
import scipy.stats as ss
