[Numpy-discussion] numpy-1.0 regress failure on OpenBSD

[Damien M. <dj...@mi...>]

Hi,

I have just got around to updating OpenBSD's numpy port from 1.0b1 to
1.0 and am running into the following regress failure:

The variable 'a' seems to contain '[Inf]', so the failure appears related to
the overflow warning.

Any clues on how I can debug this further?

thanks,
Damien Miller

Unless you want to help with tracking how long double is interpreted on 
several platforms, then just ignore the test.  (It actually wasn't being 
run in 1.0b1).

I'm happy to help - do you have a testcase that I can run on the various
platforms that OpenBSD supports?
