Tim,
I just tried everything with r3375. I set seterr(all='warn') and the tests passed. But all the floating point warning are still there. With seterr(all='ignore') the warnings go away and all the tests pass. should I worry about the warnings?
Maybe. I just sent you some email on this. But my guess is that the code that checks for FP errors is broken on your particular system. Mainly I suspect this because I think you would have noticed by now if everything was as broken as the warnings seem to indicate. Assuming that's the case, and this will probably become clear if you test a bunch of computations that give correct (and non INF/NAN) results, but still spit out warnings, you have two choices: try to fix the warnings code or disable the warnings. The former would be preferable since then you could actually use the warnings code, but it may be a pain in the neck unless you can find some place to steal the relevant code from. -tim
thanks

Also, when I use seterr(all='ignore') the the tests fail:

Thanks for helping out on this.
How recent is your version? I just a problem that was causing this same failure yesterday -- if you checkout is older than that, you may want to get the most recent stuff from SVN and see if that fixes this.
