early during InnoDB crash recovery:

InnoDB: Failing assertion: rec_get_deleted_flag(rec, page_is_comp(page))
101126  1:52:20 - mysqld got signal 6 ;

How to repeat:
InnoDB's internal stress/recovery testing of mysql-trunk-innodb, see private note.
Reproducibility is very low but there was more than one occurrence.
The assert requires UNIV_DEBUG.

This could be the most likely underlying cause of Bug#61104. The problem is that purge is attempted on a record that has not been marked for deletion.

Another possibility is that an insert is attempted by updating a delete-marked record, but the corresponding record is not delete-marked.
