[Rest of program snipped]

screen is already defined somewhere in allegro.h. Now you create a new bitmap 
called screen, but you don't do something like screen=create_bitmap (x,y).
Anytime you try to write something to a bitmap that wasn't created with 
create_bitmap or something doing the same job, something awfull is bound to 
happen.
Just delete the marked line and see where you get.
