Analyzes.

Engine support validation for compressed columns is not performed when creating tables with partition. Partitioned tables allow multiple combinations of storage engines, which is syntactically correct. When omitting table SE on non partition table, @@default_storage_engine will be used as default. But for partitioned tables, you can omit default SE, and pass a SE on partition clause. In this case, instead of using @@default_storage_engine as table SE, the SE passed on partition clause will be passed as table SE.
Current 8.0 is missing the check on partitioned tables.

Could not reproduce the issue with 5.7 build.

heh, compressed columns is supported by RocksDB? I don't think so.

create table should have failed.

can you please verify in 5.7?

8.0 triage:  Agreed, but in this case we're willing to take the risk that valid SQL also leads down the same path as this unsupported scenario.  Root cause analysis will be done after GA.

Triage, as I mentioned elsewhere, QA logs one testcase per particular crash, then filters the issue. There may be many other SQL's that can lead to a particular bug, and this issue may very well be more significant as a single testcase/situation. Please provide proper core issue analysis first before triaging.
