Corruption of the InnoDB transaction system

A colleague reminded me of two bugs that occur very rarely. We have been unsuccessful to repeat them more frequently, and reading the code has not given any ideas either. In theory, both could be related to this reported corruption of the max_trx_id:

Bug#55283 assert trx0roll.c undo_no + 1 == trx->undo_no in
trx_rollback_or_clean_all_recov
Bug#61516 Failing assertion: purge_sys->purge_trx_no <=
purge_sys->rseg->last_trx_no
