Crash when requiring streamlines

[ffeppon]

Hello, the window crash and close when I try to select a point (Maj+Middle click) and press v for a vectorial solution. Many thanks

Could you tell me more about your system ? Thanks

Dear Mr. Frey,

I have a mesh I built using mmg2ds. Then I solve in FreeFem the Navier Stokes equations and I obtain a velocity [vx,vy] defined on this mesh Thf.
Then I call medit from FreeFem with
medit("v",Thf,[vx,vy]).
The medit window opens and I am able to visualize the vector field by pressing w (by the way, it would be nice to be able to render less vectors but with bigger size when plotting on fine meshes). Then I select a point using (middle click)+Shift.
Then I get a segmentation fault when pressing v. Here is what I get from the terminal:

_Building scene(s)
Creating scene 1
Loading default options
Scene seconds: 0.11

Rendering scene(s)

Picking result :
Vertex 2831 : 0.484375, 0.484397, 0.000000 ref : 0
Data (vector): 1.449998 -0.002333

Unexpected error: Segmentation fault_

Many thanks
