Hello Steven,
thank you for your answer.
The assertion failure appears in the file xutility. This is shipped with Visual
Studio. The xutility file is responsible for some checks about the correct
initialization of arrays and iterators. Therefore I suppose that it is a
problem of initialization of objects for the included XSLT file. In the
xutility the checks which are made depend on the value of the
_ITERATOR_DEBUG_LEVEL macro. The default for this macro differs between release
and debug mode. For me this could be an explication for the different behaviour
in release and debug mode.
Furthermore I can say that the included XSLT file definitely exists. The code
where the assertion failure occurs ran in the past with Xerces 2.7.0 and Xalan
1.10 compiled with Visual Studio 2005. I never had this problem. Due to the
migration of the project to Visual Studio 2010 I did also the update of Xerces
and Xalan.
I will also create an issue in the bugtracking system you mentioned. There I
will attach a complete project containing test files to reproduce the problem.
Kind regards
Claudia
