As for the side effect by expressions as the parameter, unary operators are seldom (or never) applied to LSN. I think there's no need to fear about other (modifying) expressions, too. As a double-checking, I checked that the patch covers all output by '%X/%X' and " ?>> ?32)" that are handling LSNs, and there's no mis-replacing of the source variables. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
