IIUC the ownership patterns in Diagnostic changed relatively recently,
so (for example) the clang-interpreter is incorrect.  Currently it has:

  TextDiagnosticPrinter DiagClient(llvm::errs(), DiagnosticOptions());

  Diagnostic Diags(&DiagClient);

I think this should now be something like

  TextDiagnosticPrinter* DiagClient = new TextDiagnosticPrinter(llvm::errs(), DiagnosticOptions());

  Diagnostic Diags(DiagClient);

i.e., the destructor for Diagnostic will attempt to delete DiagClient
which might well be the crash you're seeing?
