FAIL: test_datetime_as_string (test_datetime.TestDateTime) on OpenBSD/macppc and numpy 1.9.0rc1

[didickman]

There are a few regress test failures on OpenBSD/macppc. I suspect if the simplified code below is fixed the rest will be fixed too.

Python 2.7.8 (default, Sep  1 2014, 13:25:08)
[GCC 4.2.1 20070719 ] on openbsd5
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>> date = '1959-10-13'
>>> np.datetime64(date, 'Y')
numpy.datetime64('0000')

Full regress test details below.

Hmm. What compiler? This looks like a endian or precision problem. Is the OS 32 bits?

[didickman]

Yes, OpenBSD/macppc is 32-bits. gcc is version 4.2.1:

Is it a G5? Little endian? I'm suspecting a format code...

[didickman]

It is a G4 and I believe big endian. From the dmesg:
