Description
The test innodb.innodb-index-online often fails like this on 10.6 or later branches. I suspect that it could be due to some changed timing characteristics related to MDEV-32050.

The test scenario is the KILL of the following statement:
SET DEBUG_SYNC = 'row_log_apply_before SIGNAL c2d_created WAIT_FOR kill_done'; |
CREATE INDEX c2d ON t1(c2); |
When this operation is rolled back, in row_merge_drop_indexes() we would normally have table->get_ref_count() == 1. In a failure case, a purge operation would intervene and open a table handle while row_merge_build_indexes() is blocked by the DEBUG_SYNC. This extra table handle would remain open across the rollback operation.
The following patch (which depends on MDEV-32050, where we started to ignore innodb_purge_rseg_truncate_frequency) will make the test stable for me. The first hunk makes the test ./mtr --repeat proof, for easier testing.
