At least some errors probably come from the file
sage/algebras/quatalg/quaternion_algebra_cython.pyx
and I think they should be easily fixable without any knowledge of what
is going on by just changing the code to make a copy of the zero matrix.
However, I really wonder whether this fix is neces

Hi there,
I'm close to solve: #8276 Make the one(), identity_matrix() and zero_matrix()
cached and immutable. Correcting MatrixSpace is easy, however there are a lot
of place in sage where people create a matrix from the one or zero and modify
it after that. I nearly corrected all these occu
