I believe that if you change the lines:

    CompilerInstance ci;
    DiagnosticOptions diagnosticOptions;
    TextDiagnosticPrinter *pTextDiagnosticPrinter =
        new TextDiagnosticPrinter(
            llvm::outs(),
            &diagnosticOptions,
            true);
    ci.createDiagnostics(pTextDiagnosticPrinter);

to simply:

    CompilerInstance ci;
    ci.createDiagnostics();

the problem will go away. I'm not sure why clang allows the current call,
as the interface changed.
