Changelog category (leave one):

  • New Feature
  • Bug Fix
  • Improvement
  • Performance Improvement
  • Backward Incompatible Change
  • Build/Testing/Packaging Improvement
  • Documentation (changelog entry is not required)
  • Other
  • Not for changelog (changelog entry is not required)

Changelog entry (a user-readable short description of the changes that goes to CHANGELOG.md):

...

Detailed description / Documentation draft:

...

By adding documentation, you'll allow users to try your new feature immediately, not when someone else will have time to document it later. Documentation is necessary for all features that affect user experience in any way. You can add brief documentation draft above, or add documentation right into your patch as Markdown files in docs folder.

If you are doing this for the first time, it's recommended to read the lightweight Contributing to ClickHouse Documentation guide first.

This use-after-free can be reproduced with distributed queries.

Also note, that this is not sumMappedArray() and friends (that
previously called sumMap()) but Map combinator.

You will find ASan report in details.

…y names

When ClickHouse encounters a distributed table directory with a name that:
- starts with the pattern `shardN_all_replicas` (e.g., `shard3_all_replicas_bkp`)
- but doesn't end with exactly `_all_replicas`

It would crash with a segmentation fault due to out-of-bounds array access.

Trace example:
```
