It looks like you have gcc 7.2.0 on your system. Are g++ and gfortran the
same version? Perhaps try rebuilding Sage (after running

Hi,
In Sage 8.1.beta8 and all previous versions (at least down to 7.5.1), we
have
sage: s = function('f')(x) * x^2
sage: s.coefficients(x) # OK
[[f(x), 2]]
sage: s = diff(function('f')(x), x) * x^2
sage: s.coefficients(x) # Bam!
Erreur de segmentation (core dumped)
Is this a known bug?

This sounds a very good idea!
I could possibly take part in these Sage Days and give an introductory
course
Hi,
if you want to make explicit that you apply the operation to each entry,
you can still do:
sage: A = Matrix(ZZ,2,[3,3,3,3])
sage: A.apply_map(lambda x:x//3)
[1 1]
[1 1]
sage: _.parent()

This method works for many things, that migh
Enabling // just for Euclidean rings is fine for me.
Or let's say A//k is defined if // is defined on the entries of A? (which
should include euclidean rings).
And if it is not then one has to do the ugly conversion by hand if one
really wants it.
