Comment (by charris):

 Hah, thought so. I'm going to guess it's a 64 bit thingee, maybe involving
 64 bit integers in a parameter somewhere in the Atlas call. The cov code
 is pretty simple, the only place that looks like a problem is:

     if not rowvar:
         return (dot(X.T, X.conj()) / fact).squeeze()
         return (dot(X, X.T.conj()) / fact).squeeze()


 Could you try the dot products with your matrix leaving out the fact
 variable and the squeeze method?
