[GRASS-user] grass 7.0 v.isochrones : error message

[image93]

Dear friends,

I 'm working with grass 7 on windows 7 32 bits. I loaded into grass OSM data
for driving isochrone. I selected only usefull roads : primary, secondary,
etc. And moreover, i create a max speed field thanks to the type of the
road. 

I succed in loading start point and raod network OSm into grass. 

But when i run the v.isochrones with r.cost method, grass crashes and the
following error message appears :

What is the meaning of the message? I'm really surprised. Four months ago, i
tried to generate isochrones with the same method, same tool, same soft
without problem. And today, i am not abble to reproduce the process without
error message...

Could you help me? 

Thanks.
