Comment (by mjo):
It does fail eventually; I must have had extraordinarily bad luck. It's
hard to imagine that I ran that test fewer than 100 times, but once I
moved it into a smaller file and ran with `--file-iterations=500` it
failed.
For it to fail you need `random_cone` to give you a nontrivial cone with a
nontrivial lineality space that isn't equal to the entire cone. Then
`random_element` has to assign nonzero coefficients in the right places. I
guess I can believe it, even though 100 is a very conservative estimate.
