mysqltest on Windows hangs and eventually cores during DROP COLUMN on partitioned table

[chyujing]

Environment

• Platform: Windows
• Test Suite: mysqltest
• Reproducibility: Stable (100% reproducible)

Description

During the execution of the mysqltest case ddl_drop_mysql_sqlqa.drop_column_pratition_range_list_mysql on a Windows system, the test process hangs indefinitely when performing a DROP COLUMN operation on a partitioned table. The process eventually crashes (cores) after a prolonged period.

Steps to Reproduce

1. Connection: Use the MySQL client to connect to the instance.

   mysql -uroot -h -P 2881

2. Execute Test Case: Run the specific mysqltest case.
   • Case Name: ddl_drop_mysql_sqlqa.drop_column_pratition_range_list_mysql

Observation: On the Windows version, the test execution hangs at the DROP COLUMN step. If left waiting for an extended period, the process eventually crashes (cores).
