> Project: XalanC
> Type: Bug
> Components: XalanC
> Versions: 1.9
> Environment: Xerces 2.6 (9/30/2004)
> Xalan 1.9 (12/22/2004)
> Os: Windows 2000 Advanced Server
> Compiler: Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.3077

> Transforming an XML DOM document encapsulated within an
> XercesDOMWrapperParsedSource object triggers an invalid heap pointer
> exception if XSL opens other XML document with 'document()' function.
> The XML is parsed and stored in an XercesDOMWrapperParsedSource object.
> The XSL style-sheet opens with the function 'document()' an other XML
> document.
> The transformation itself goes ok. When the destructors are called, an
> 'delete' is deleting memory in a wrong heap.
> The behaviour does not occur with Xalan 1.8
> The behaviour does not occur when the XSL style-sheet does not open an other
> XML document.
> The behaviour does not occur when the XML is not stored in an
> XercesDOMWrapperParsedSource object.
