Commit 9aedb0c61f changed this from allocating off `c` to allocating
off NULL, knowing that it's tal_steal() in the callback. But before
that, it can be detected as a mem leak:
```
@pytest.fixture
def teardown_checks(request):
"""A simple fixture to collect errors during teardown.
We need to collect the errors and raise them as the very last step in the
fixture tree, otherwise some fixtures may not be cleaned up
correctly. Require this fixture in all other fixtures that need to either
cleanup before reporting an error or want to add an error that is to be
reported.
"""
errors = TeardownErrors()
yield errors
if errors.has_errors():
# Format a nice list of everything that went wrong and raise an exception
request.node.has_errors = True
> raise ValueError(str(errors))
E ValueError:
