The API doc says:
"void XMLPlatformUtils::Initialize () [static]
Perform per-process parser initialization."
so I assume it isn't mean to be called repeatedly.
It is also written at http://xml.apache.org/xerces-c/program.html
"Key points to remember when using the C++ DOM classes:
- Create them as local variables, or as member variables of some
other class. Never "new" a DOM object into the heap or make an
ordinary C pointer variable to one, as this will greatly confuse
the automatic memory management. "
So that might be your problem.
You should just create your parser like:
DOMParser myDOMParser;
and you don't need to delete it. If you really want two of
them with the same name, you can put them in their own code
blocks with {}.
I thought I noticed a similar problem in my own project
without using new. It went away when I moved my call to
XMLPlatformUtils::Terminate() to where it would only occur
once. (As it happens I am happily calling XMLPlatformUtils::Initialize()
multiple times with no apparent problems. I will be making that
go away shortly.)
