| 12:46 | Make sure an imbalance in the number of columns on a compound SELECT is detected and reported as an error before it can cause an assertion fault or array-bounds overflow in the code generator. Oops: part of the fix for ticket #3015 got included with this check-in by mistake. (CVS 4917) check-in: 50de87dc user: drh tags: trunk | |
