> Hi,
> I just downloaded fig1.4-fs and tried it. I created a figure with 65
> objects and saved it to a file. Later on, when I tried to read the file
> again, the program crashed. I traced the problem to read_lineobject which
> gets called when figs reads the input file. The problem is with Point_malloc
> which allocates space for x,y coordinates plus a pointer to the next
> coordinate. If the line has only one point, there is the possibility that
> the pointer points to some bad address. To correct the problem, insert
>
> p->next=NULL
>
> after Point_malloc gets called (around line 441 in read.c).
>
> Hardware: Sun 3/60 color, SUN OS4.00 (we're still waiting for the
> 4.01 tapes!!).
>
> It is possible to have lines with a single point. Just create a
> POLYLINE that starts and ends at the same pixel.
