| 18:21 | Ensure that the sqlite3StrAccumAppend() routine is never called with a NULL second argument. Doing so is harmless when N==0, but it causes an assert() to fail that was placed to quiet static analyzers. (Closed-Leaf check-in: f03fbf37 user: drh tags: tkt-55746f9e) | |
| 17:19 | Make sure the group_concat() function returns an empty string, not a NULL, if it has at least one input row. Fix for ticket [55746f9e65f8587]. (check-in: 0deac873 user: drh tags: tkt-55746f9e) | |

First intended use is in test programs for the memory allocation logic where one does not want to allocating a _FAST or _RECURSIVE mutex since that would involve using the memory allocation system under test.
