PDOStatement::bindParam() and bindColumn() leak references on the driver_params argument: register_bound_param() never releases its transient copy, and really_register_bound_param() drops its hash-bound reference on neither of its two early failure returns, so 200k failing bindParam() calls grow memory by about 128MB and even successful calls leak one reference each. Both paths now release what they take; the EVT_ALLOC hook failure needed no change because deleting the hash entry frees it through param_dtor().
