I overlooked note

"""
Make sure you keep references to CFUNCTYPE objects as long as they are
used from C code. ctypes doesn’t, and if you don’t, they may be
garbage collected, crashing your program when a callback is made.

If I defined errtype and errfunc as global variable everything works.
Thanks again for your help. Martin
