Comment(by strk):

 Ok, I could reproduce by running ST_Intersects(A, A) OR ST_Intersects(A,
 P).

 Interesting enough the leak remains in the A-A case, doesn't matter if A-P
 is encountered, so the problem is fully with the prepared geometry cache,
 not the RTREE one. Which is the confusing function, btw. This is with
 ST_Intersects though (as the reporter for r8877 regression uses), not
 ST_Contains (which does _not_ seem to leak for me).
