Hi Andres,

please try the latest trunk (at least r66460 [1, 2]). Can you please try to
create a Bash script or a Python script which would prepare some data or
use data from NC basic/small Location [2] and run v.what.vect in the same
way as you were running it? In this way we can see if the recent changes
provide expected results.

Thanks,
Vaclav
