  Changed paths:
    M test/recipes/80-test_cmp_http.t

  Log Message:
  -----------
  Prevent 80-test_cmp_http from accidentally killing perl in error.

If there is an issue with setting up the test environment in this test,
pid is not set so stop_server kills the perl process. A guard has been
added to prevent this situation.

Fixes: #22014
