#42 Graph Demo zoom crash

[Julian H J Loaring]

Under Windows XP and Windows NT 4.0 SP6 the graph1.tcl demo crashes
if you repeatedly zoom in. Typically it takes over 8 zooms sometimes
> 14. The error given is that Wish is "Unable to alloc - xxx
bytes"
where xxx is a large number.

Also tried Mandrake 8.2
using Tcl8.3.4 and latest BLT CVS and this also fails when zooming in
many times (using graph1.tcl).

This time we get
