Comment 36 for bug 1570923

Please note that the above fixes do make Bacula run, but as was discovered in bug #1592749, MySQL runs ~10 times slower than it should. I attach a patch here and in the other bug as well that fixes this problem. The patch is relative to released version 7.4.1, and may (I am not sure) apply correctly after your patch is applied -- in fact, it is a one line addition to my original patch (yours also I think). See bug #1592749 for more details on why this patch is also needed.
