Overview
Comment: | Oops - the deephemerialization needs to occur before the move, not after. Was: Rather than try to keep track of the parent of an ephermeral register when the register moves, just deephemeralize all registers touched by the OP_Move opcode. |

13:11 | Oops - the deephemerialization needs to occur before the move, not after. Was: Rather than try to keep track of the parent of an ephermeral register when the register moves, just deephemeralize all registers touched by the OP_Move opcode.

12:44 | Shift the Mem.pScopyFrom pointer in the correct direction in OP_Move. Fix for a defective check-in [a2135ad13049] and ticket [d6352363751]. Debugging code only - does not affect normal operation. (check-in: add4e043b3 user: drh tags: trunk) | |
