[GRASS5] grass57 d.what.vect - dies silently after two clicks

[Moritz Lennert]

Hello,

d.what.vect does not give any results and dies silently after the second
click on the map.

When launched via the display manager, the following error message appears:

child killed: write on pipe with no readers
