That's the bug.

Is there a reason these tests don't seem to be disabling coredumps?

I am not sure the test failure is because of the crashes - the test spawns VMs that ought to crash. The failure reason seems to be the timeout of the driver (given that there are three core files but only two hs_err files, i.e. two hs_err and core files for the intentional crashes and one additional core file for the timeout).
