Hm, this is very strange. Do you catch all the exceptions, including
the Xerces-C++ ones? If that's the case, then chances are high this
is an access violation exception (will also explain why you sometimes
get just the incorrect behavior without an exception).

Ideally, you would want to run this application under a debugger (or
let it crash and then load it into the debugger to examine the stack
trace) to figure out what kind of exception it is.

You could change your code to send the output XML as input. Then parse
it to DOM and serialize it back to XML.
