Two years later I forgot about this issue and I found it again with 
lazarus 3.2 and a freshly downloade vampyre imaging library (which is 
still at version 0.80 in the online package manager, though I see that 
the line is still there in the github repository).

Probably my fault for not reporting the issue to  Vampyre, I just hope 
my memory serves me better next time.

Bye
