I assumed that the default behaviour was that exceptions are thrown
when a fatal error is encountered, which is IMHO normal C++ library
behaviour. That was of course a false assumption. I compiled and
executed the same code again, but now with an implementation of
ErrorHandler set, and everything works very well.
Thanks for your help,
