## Proposed changes
When executing broker load in ASAN mode, BE may crash with error:
```
F20231010 18:18:17.044978 185490 block.cpp:694] Check failed:
d.column->use_count() == 1 (3 vs. 1)

```
It may happen when there is column maping like:
```
(k1,v2,v3,v4,v5,v6,v7,v8)
set (k2=v4,k3=v4,k4=v4)
```
in load stmt.
Case is covered by Baidu test cases
