I wonder if there's a way to add some consistency checks into the (active) replay machinery. Like, maybe we could, for each function that returns an SBError, record a flag saying whether that error was in a success state or not. Then if this flag differs during replay, we know that we have started to diverge and can stop replaying (or at least give a very loud warning about it).

Comment at: lldb/source/API/SystemInitializerFull.cpp:46
+    if (repro::Reproducer::Instance().IsReplaying())
+      std::_Exit(EXIT_FAILURE);
+    return error;
Print the error that has happened? maybe via `report_fatal_error` ?
