Steps to reproduce issue

  rcl_ret_t rv;

  rcl_init_options_t options = rcl_get_zero_initialized_init_options();
  rv = rcl_init_options_init(&options, rcl_get_default_allocator());
  if (RCL_RET_OK != rv) {
    printf("rcl init options error: %s\n", rcl_get_error_string().str);
    return 1;
  }

  rcl_context_t context = rcl_get_zero_initialized_context();
  rv = rcl_init(argc, argv, &options, &context);

Above code in combination with a 'rmw_init` implementation which returns something that is not RMW_RET_OK,

Expected behaviour

It should fail gently setting errors accordingly.

Actual behavior

Segmentation fault in:

Additional information

The dump is generated due to allocator being 0.

Combination of

but it is setting the allocators in a different line.
