> Project: Xerces-C++
> Issue Type: Bug
> Components: Miscellaneous
> Affects Versions: 3.0.0, 3.0.1
> Reporter: peter
> Assignee: Boris Kolpackov

> The destructor of LocalFileFormatTarget is calling flushBuffer() which in turn may throw exceptions. Throwing exceptions in dtor however is dangerous since it may lead to program termination if the exception is thrown during stack unwind.
> Example: DOMLSSerializer::writeToURI() is causing imediate program termination if there is no space left on disk. The reason is an exception thrown in DOMLSSerializer::write(). During stack unwind the dtor of LocalFileFormatTarget is called throwing another exception which is illegal and leads to program termination.
