When executing a concurrent DDL workload + transactional LOCK TABLE, mysqld asserted as follows:

mysqld: sql_class.h:1997: void THD::fatal_error(): Assertion `main_da.is_error()' failed.

See also bug 45067 which is about a similar assertion in a similar situation.

How to repeat:
If this is repeatable, a test case will be provided. In the meantime, the core and the binary will be made available.

I am setting this to Verified with the expectation that diagnostics_area bugs can be debugged based on core file alone, or that this bug will be closed as a duplicate to the previously reported DA bug involving killing delayed insert.
