Subject: Bug #27084 partitioning by list seems failing when using case

creation of the partitioned table could fail as we created Item-s for
it's list function in thd->mem_root, and then do Item->fix_fields
in the context of other table->mem_root (so that memory alloced
there was alloced in this table->mem_root). As we freed the
table->mem_root before we do thd->free_items, our Item-s had
pointers to the freed memory, that caused the crash
