Thank you Gabor,

I didn't realize it while reading the doc: since VAN is a shortcut to 
igraph_cattribute_VAN (which returns igraph_real_t) I should have 
thought of this.
Usually I compile with -Wall, but this time, I simply forgot.

I guess I am a bit more rusty with C than I thought!

Thank you again,
