listctrl set_item_data
Hi,
I have used set_item_data with ruby objects (an array) and got a crash.
The reason is simple, the objects were deallocated by the GC.
The easy solution would be to accept only long parameters (like the
original interface).
The hard is to play by the GC''s rules and increase the reference count
and decrease on deletion.
Regards,
teki
