> Hi all,
I am delaying a Mandriva sagemath 4.6.1 due to related reasons,
and may not release it if sagemath 4.6.2 is released soon :-). Since
Mandriva cooker is using python 2.7.1 and cython 0.14, I needed to
use a custom cython 0.13, but am trying to correct some issues with
python, to use python 2.7.1.
Just adding unittest.py from python2.6 to PYTHONPATH, that points
to /usr/share/sage/site-packages corrected like 90% of the problems,
but just now I got this one in
sage/rings/polynomial/polynomial_quotient_ring_element.py
[[ cut&paste of test case in sage under a python in gdb
slightly different than sage -gdb, but effectively the same ]]
-%<-
sage: R.<x> = PolynomialRing(QQ)
sage: sage: S.<a> = R.quotient(x^3-2)
sage: sage: int(S(10))
10
sage: int(a)
Fatal Python error: GC object already tracked

I have "gfan-0.4plus" packaged, so, do not see this one...

Yes, and I also do not have this problem because of not updating
it...
A good share of packages I only update when sagemath updates,
but other packages are updated by other people, or, I myself would
update to latest upstream, but in the case of sage, I would first
test...
I also get a massive number of rounding ones, like:
-%<-
File "/usr/share/sage/devel/sage/sage/finance/time_series.pyx", line 1550:
sage: v.variance()
Expected:
0.80000000000000004
Got:
0.8
-%<-
File "/usr/share/sage/devel/sage/sage/finance/markov_multifractal.py", line 99:
sage: msm.m0()
Expected:
1.3999999999999999
Got:
1.4
-%<-
File
"/usr/share/sage/devel/sage/sage/schemes/elliptic_curves/ell_rational_field.py",
line 2134:
sage: F.CPS_height_bound()
Expected:
0.65551583769728516
Got:
0.6555158376972852
-%<-
