// In a non-forking sandbox, we can't spawn an external symbolizer, but dladdr()
// should still work and provide function names. No line numbers though.
// Second, `atos` symbolizer can't inspect a process that has an inaccessible
// task port, in which case we should again fallback to dladdr gracefully.
