Emitting multiple documents with tags fails

[ShaiWavesAudio]

The following code attempts to emit 2 documents each with a local tag:

    YAML::Emitter theEmitter;
    for (int i = 0; i < 2; ++i)
    {
        theEmitter << YAML::BeginDoc;
        theEmitter  << YAML::LocalTag("The_Tag");
        theEmitter  << YAML::BeginSeq;
        theEmitter  << "Some Value";
        theEmitter  << YAML::EndSeq;
        theEmitter  << YAML::EndDoc;
    }
    std::cout << theEmitter.c_str() << std::endl;

I expected the code to print:

--- !The_Tag
- Some Value
...
--- !The_Tag
- Some Value
...

However the actual print is:

--- !The_Tag
- Some Value
...
--- !The_Tag

It looks like the call to YAML::LocalTag("The_Tag") leaves the emitter in an error state - however no exception is thrown.

If I remove the call to YAML::LocalTag("The_Tag") the print is OK:

---
- Some Value
...

---
- Some Value
...

I'm using yaml-cpp 0.5.2 with Xcode 5 on Mac OS 10.9.
Does not happen with yaml-cpp 0.3.0.

Thanks,
