A prepared statement object is created and associated with a
GdaStatement when the GdaStatement is being executed (if the same
GdaStatement is executed several times, then the same prepared
statement object is reused). The prepared statement is destroyed when
either the GdaStatement changes or is destroyed, so there should not
be any mem leak there, but of course there may be bugs...

Do you have a test case from which I can investigate?
