Segmentation fault after referring a freed-up node

[Unniboy]

Using the example in README, there are at least 2 ways to hit segmentation fault, using v3.0.2.
Requesting a fix or guide towards proper usage if the below seems incorrect.
Intention is to delete nodes based on some conditions.

>>> import libyang
>>> ctx = libyang.Context()
>>> module = ctx.parse_module_str('''
module example {
  namespace "urn:example";
  prefix "ex";
  container data {
    list interface {
      key name;
      leaf name {
        type string;
      }
      leaf address {
        type string;
      }
    }
    leaf hostname {
      type string;
    }
  }
}
''')
>>> node = module.parse_data_dict({
    'data': {
        'hostname': 'foobar',
        'interface': [
            {'name': 'eth0', 'address': '1.2.3.4/24'},
            {'name': 'lo', 'address': '127.0.0.1'},
        ],
    },
})
>>> nodes = list(node.find_all("/example:data"))
>>> nodes[0].free(with_siblings=False)
>>> print(node.print_mem('json', pretty=True)) # OR print(node.find_path("/example:data"))
