2010/04/08 - stmane: src/backends/monet5/sql_scenario.mx,1.372.2.3
fixing ID: 2983773 "SQL: minimal optimizer pipe unstable"
https://sourceforge.net/tracker/index.php?func=detail&aid=2983773&group_id=56967&atid=482468
In the code of and related to setOptimizers(),
make sure we use GDKstrdup() & GDKfree() only when indeed required
and thus not only prevent double free's
but also avoid memory leakage.
