Memory leak in TiXmlDocument::LoadFile()?

I noticed that TiXmlDocument::LoadFile( const char* fileName ), a new FileStream object is being allocated, but is not being released (at least, not that I can see).

This line:

diskStream = new FileStream;

Someone please correct me if I am wrong, but this line needs be somewhere in there:

delete diskStream;

I am currently using iTorque 1.4.
