If some recursive member used indexed (rsb_indexed) or navigational (rsb_navigate) access path then memory leak is possible.
Memory leaked from request's pool therefore it is visible if some prepared statement executed many times.
Also it is visible if procedure or trigger used recursive query.

====== Test Details ======

One need to query mon$memory_usage before and after such query, but mon$ tables did appear in 2.5.0 and this ticket was already fixed in 2.5 BETA 1.
