to each other. This should remove some infrequent teardown crashes when the listener is not the debugger's listener. Processes now need to take a ListenerSP, not a Listener&. This required changing over the Process plugin class constructors to take a ListenerSP, instead of a Listener&. Other than that there should be no functional change. <rdar://problem/24580184> CrashTracer: [USER] Xcode at …ework: lldb_private::Listener::BroadcasterWillDestruct + 39 llvm-svn: 262863
