[arrayIndexThenCheck] Did your static analyzer not notice that this dead code is not even compiled? I don't have a lot of faith in analyzers that ignore #ifdefs. (It's fair to ask why we haven't removed this code altogether ... laziness I guess, or waiting for something better than GEQO to come along. But expending effort on fixing it is definitely not in the cards.) regards, tom lane ^ permalink raw reply [nested|flat] 2+ messages in thread
