Bug Description
Dynamic row format feature to support BLOB/VARCHAR in MEMORY tables requires all the key columns to come before any BLOB columns. This requirement however is not enforced, allowing creating MEMORY tables in unsupported column configurations, which then crash or lose data in usage.
This has been causing bug 1706356, bug 1628964, bug 1629320
