Comment(by fredrik.johansson):
Memory usage grows to a few hundred megabytes (which is strange, but not
necessarily a bug by itself), but I have 3GB of RAM so it shouldn't be a
problem.
I wonder if this might be related:
{{{
sage: A = MatrixSpace(RDF,1000,1000).random_element()
sage: B = MatrixSpace(RDF,1000,1000).random_element()
sage: C = A * B
