It took me a while to get lldb to run emacs (missing get-task-value entitlement), and then:
running under lldb, emacs doesn’t crash, but it also doesn’t open any frames:

Without lldb:

Could you please give me a hint, how to start Emacs under lldb so that it behaves the same as if started interactively ?
