FRM file corruption caused by killed ALTER TABLE

Scenario:
1. Start the server and create some table.
2. One session runs a loop consisting of
ALTER TABLE ... ADD COLUMN ... ;
ALTER TABLE ... DROP COLUMN ...;
The other session runs a loop consisting of
KILL SOFT QUERY <first session>
After some short time the server error log starts to fill up with entries like
2025-11-12 10:34:17 16 [ERROR] mariadbd: Incorrect information in file: './test/#sql-alter-376c5c-10.frm'
2025-11-12 10:34:17 16 [ERROR] mariadbd: Incorrect information in file: './test/t5.frm'
It does not matter if the tables uses the storage engine InnoDB, Aria or MyISAM.
