Re: [sage-devel] deterministic "ordering" of subsets (py3)
Python 3 introduced randomness in their base hashing functions. That
impact strings.
$ python -c 'print(hash("hello Daniel!"))'
-4203807413548925149
$ python -c 'print(hash("hello Daniel!"))'

I just was hunting a Heisenbug related to Python3. It boils down to the
following:
dakrenn@nops:~$ /opt/sage/8.5.beta2-python3/sage -c "P. = QQ[]; S
= Set([x,y,z]).subsets(2); print(S); print(list(S))"
Subsets of {y, x, z} of size 2
[{x, y}, {z, y}, {z, x}]
dakrenn@nops:~$ /opt/sage/8.5.beta2-python3/sage -c "P. = QQ[]; S
= Set([x,y,z]).subsets(2); print(S); print(list(S))"
Subsets of {z, x, y} of size 2
[{z, x}, {z, y}, {x, y}]
dakrenn@nops:~$ /opt/sage/8.5.beta2-python3/sage -c "P. = QQ[]; S
= Set([x,y,z]).subsets(2); print(S); print(list(S))"
Subsets of {y, x, z} of size 2
[{y, x}, {y, z}, {x, z}]
So the order in which the subsets appear is random (and also the order
in the sets). I was wondering why this order is *now* (Python3) random,
but was not before:
dakrenn@nops:~$ sage -c "P. = QQ[]; S = Set([x,y,z]).subsets(2);
print(S); print(list(S))"
Subsets of {y, z, x} of size 2
[{y, z}, {y, x}, {z, x}]
The result in Python2-SageMath was the same for roughly 10 runs (for
Python3 above, three runs three different results).
(My question is also because there is an order on the elements
themselves, namely z < y < x. And I am aware that sets are unordered so
ordering is not to be expected, but still there is this change and I was
wondering why (as the elements themselves are still comparable in
Python3-SageMath.)

Re: [sage-devel] Sage 8.4 does not compile / CentOS 6.10
I did what you suggest:
installing a newer version. The newest I could find for my CentOS is:
gcc (GCC) 4.8.2 20140120 (Red Hat 4.8.2-15)
Then for the first time it goes further and further. Took hours! but it
finally stopped there (also in attachment the log file):
