Niels, this checkin adds "div_by_zero_in_return.Bug-3555" (in addition to "orderby_on_constant.Bug-3554") to sql/test/BugTracker-2014/Tests/All but does not add the respective files (div_by_zero_in_return.Bug-3555.*). Do you have these files ready, or should we remove "div_by_zero_in_return.Bug-3555" from sql/test/BugTracker-2014/Tests/All ? The respective bug report is still open: https://www.monetdb.org/bugzilla/show_bug.cgi?id=3555 Thanks! Stefan ----- Original Message -----
