Description:
I try to run an alter table query on a a table with 700K rows, 5 columns, and a primary key column, using "ALTER TABLE xx ADD COLUMN (x INT);", which is a pretty simple task. 

It takes minutes and the "mysql workbench unexpected error" window pop-up. 

It shows "Index was out of range. Must be non-negative and less than the size of collection" and "Parameter name: index". 

I doubt whether it is because the query takes too long, longer than the limitation of query execution. However, since it is not a huge table, I did expect the execution time to be such long. I am not sure whether it is workbench issue or mysql server issue. 

How to repeat:
Run the query again.
