No, this is wrong. See prep_alter_part_table(). The first thing it does it to copy thd->lex->part_info to thd->work_part_info. It tries to do a deep copy to be able to modify it freely, but apparently the copy isn't deep enough. I see two options 1. Do a deeper copy. Duplicate all value lists. 2. Make part_column_list_val elements immutable. That would be preferred, of course, but I'm not sure it's possible.
