Description
PrimProc multi_token reading is breaking when reusing the same token. This causes junk data on a select on a multi-row table using TEXT/BLOB data longer than 8KB. Observed when doing an UPDATE on a constant column. Example:
MariaDB [test]> update b3 set b = repeat('hello world ', 5000);
|
Query OK, 7 rows affected (47.60 sec)
|
Rows matched: 0 Changed: 0 Warnings: 0
|
 |
MariaDB [test]> select a, length(b) from b3;
|
+------+-----------+
|
| a | length(b) |
