Allegro primitives 5.0 - memory leak?

My program draw simple primitive by al_draw_prim(...); function and sometimes one of vertices are crazy dancing :O is this memory leak in al_draw_prim() or something like that?

Visual 2010, Code Generation MT, release

Another question is, how can I draw bitmap bigger than it is and repeat bitmap ( like a texture ). Is it only primitives way?

I don't see where you're setting the z values of the vertex in 3d space.

They all watch too much MSNBC... they get ideas.
