Without diving into the details of your test program, I get the same results on
a 64-bit Debian Python 2.7.9 as with a 64-bit OS X 2.7.10:
c_uint32 TESTS:
Class Name exponent number Sign float
binary repr
IEEE754Float_u ('-0x7b', '0xbeb2aL', 0L, 69.95930480957031, ['0x42', '0x8b',
'0xeb', '0x2a'])
IEEE754Float_u ('-0x7b', '0xbeb2aL', 0L, 69.95930480957031, ['0x42', '0x8b',
'0xeb', '0x2a'])
AN575Float_uint ('0x0', '0xbeb2a', 0L, 1.094551427887186e-39, ['0x0', '0xb',
'0xeb', '0x2a'])
AN575Float_uint ('0x0', '0xbeb2a', 0L, 1.094551427887186e-39, ['0x0', '0xb',

IEEE754Float_u ('-0x7b', '0xbeb2aL', 1L, -69.95930480957031, ['0xc2', '0x8b',

But using the same OS X 2.7.10 in 32-bit mode, I get:
