| 11:47 | Fix a harmless use-of-initialized-value fault in the assert() logic added by check-in [d612fb7873cf59d] check-in: 3dac9072 user: drh tags: trunk | |
| 03:47 | Fix harmless compiler warning in the session extension. check-in: dff823ca user: mistachkin tags: trunk | |
| 01:22 | Make sure the OP_Concat opcode always correctly zero-terminates a UTF16 string, even if the input strings are ill-formed. This is a followup to check-in [3a16ddf91f0c9c516a7] that fixes a case the previous check-in missed. Also add assert()s to prove correct zero termination. check-in: d612fb78 user: drh tags: trunk | |
