One fairly common cause of errors that involve memory allocation in
Xerces-C++ is the uninitialized runtime. If you are initializing
it yourself, then can check that it is not terminated before you
call your last parser?

Also, if your application is multi-threaded and you don't initialize
the Xerces-C++ runtime, then you most likely should in order to avoid
race conditions (which could also cause the above error). If you make
this change, also make sure you pass the dont_initialize flag to the
document's parse() functions:
