Description Rafael Fonseca 2015-09-21 12:47:03 UTC 
Description of problem: some tests fail only in ppc64 (ppc64le is fine). This is the output from ppc-koji:

Version-Release number of selected component (if applicable): 1.0.4-1


How reproducible: ppc-koji build python-astropy in ppc64.


Additional info: I modified the equal_data function like this:

def equal_data(a, b):
    for name in a.dtype.names:
        if not np.all(a[name] == b[name]):
            print('a', a)
            print('b', b)
            print(name, ':', '#', a[name], '#', '@', b[name], '@')
            return False
    return True

and this is the output:
