> We faced a crash in ElemComment::endElement because method iterator XalanVector::insert(iterator thePosition, const value_type&   theData) returns invalid iterator.
> Our testcase has a quite complex xslt-files, but in short description we transform two XML-files with the same xslt-file. And Xalan crashes on second transformation while "fix up any occurrences of the sequence '--' in the comment's data by inserting a space between them".
> Here is the bug description.
> Bug place callstack:
> XalanVector::insert
> XalanDOMString::insert
> ElemComment::endElement
> ElemTemplateElement::execute
> StylesheetRoot::process
> XSLTEngineImpl::process
> XalanTransformer::doTransform
> XalanTransformer::transform
> we fall into the "true" branch of "if (m_allocation > m_size)" thus calling "insert(thePosition, 1, theData);" and returning old iterator thePosition.
> But in XalanVector::insert(iterator thePosition, const value_type&   theData) we fall into the "true" branch of "if (theTotalSize > capacity())" which creates new vector and swaps it with "this". Therefore thePosition iterator becomes invalid.
