DOMWriter heap corruption

[Westy]

Hi,

I'm using Xerces 2.7.0, with Visual Studio 2005.

I am experiencing what appears to be a heap corruption issue with the
DOMWriter in the code below, the error doesn't occur until main() is
exitting.

I read where others had similar issues, but their problems seemed to go away
when then added a call to release() of the DOMWriter.  I have the call to
release and still have the same issue.

Does anyone see anything else I'm doing wrong?

Incidentally, I had the same issue with using the latest code from Xerces
3.0.0 and the DOMSerializer, so it might be something I'm not doing in terms
of memory for the std::string ..

Thanks,

-Westy
