Glynn,
thank you very much for your response!

I think I understand what you are saying, but:
- my vectors lie completely within the raster.
- the error occurs when the region is set to the extent of the raster  
as well as when it is set to the extent of the vectors.

So, how can it be that Vect_get_node_coor() returns coordinates  
outside the current region?

And how can it be that the error occurs even though the node really  
lies within the current region:
