Comment:
the attached {{{trac_12171a.patch}}} fixes all issues but two on 64-bit.
The remaining issues
are related to {{{loads(dumps(b)) == b}}}:
{{{
File
"/usr/local/sage-4.7.2/sage/devel/sage-12171/sage/rings/real_mpfi.pyx",
line 1084:
sage: loads(dumps(b)) == b
Expected:
True
Got:
False

line 1088:
sage: loads(dumps(b)) == b

True
Got:
False
}}}
I see in {{{real_mpfi.pyx}}} that other similar tests are failing and were
rewritten in a
different way:
{{{
sage: R = RealIntervalField(4000)
sage: s = 1/R(3)
sage: t = loads(dumps(s))
sage: (t.upper(), t.lower()) == (s.upper(), s.lower())
True
}}}
Indeed {{{t==s}}} fails:
{{{
sage: t == s
False
}}}
Should I also rewrite the 2 failing tests like this? What is the reason
for the failures?
