Comment:
Thanks, this test passes now! It was the float128 indeed...
If you still need the info:
print(numpy.finfo(numpy.float128))
Warning: overflow encountered in add
Warning: invalid value encountered in subtract

Machine parameters for float128
---------------------------------------------------------------------
precision= 75 resolution= 1e-75
machep= -4 eps= 1.3817869701e-76
negep = -4 epsneg= 1.3817869701e-76
minexp= -1 tiny= -1.08420217274e-19
maxexp= 1 max= -9.22337203471e+18
nexp = 1 min= -max
---------------------------------------------------------------------
compared to i386:
print(np.finfo(np.float128))
Machine parameters for float128
---------------------------------------------------------------------
precision= 18 resolution= 1e-18
machep= -63 eps= 1.08420217249e-19
negep = -64 epsneg= 5.42101086243e-20
minexp=-16382 tiny= 3.36210314311e-4932
maxexp= 16384 max= 1.18973149536e+4932
nexp = 15 min= -max
---------------------------------------------------------------------
The tiny and max certainly seem wrong, but maybe it's just print() can't
handle them?
Anyway the other failures (notably fpe 'overflow' and 'underflow' for
numpy.float128) are still present on ppc.
Cheers
