Comment:
Replying to [ticket:2438 artegion]:
> calling Vect_get_line_type with line out of range (i.e. line=0)
> Vect_line_alive returns -1 but Vect_get_line_type ignores it (not -1 is
False just like not 1) -> access violation reading ....
This is a programmer's error. 'Vect_get_line_type()' assumes that the
programmer first tested if the provided line id is indeed valid. You did
call 'Vect_line_alive()' first, you can only proceed if the line is alive.
Fix your code.
