error: "cannot allocate memory" during test

[Martin Pool]

I'm not sure if this is reproducible, just thought I would post it in
case anyone else saw it.

I have some doubts about the stability of the machine this is running
on so it might be a hardware problem.

This test shouldn't be using large amounts of memory but it's possible
something has leaked from a previous test.

Possibly we should invoke gc between each test, in case a lot of
memory has been used or also to give any destructors a chance to eg
warn that objects were not released?
