Bug #32709: Assertion failed: trx_data->empty(), file log.cc

Browse Source 
The assertion indicates that some data was left in the transaction
cache when the server was shut down, which means that a previous
statement did not commit or rollback correctly.

What happened was that a bug in the rollback of a transactional
table caused the transaction cache to be emptied, but not reset.
The error can be triggered by having a failing UPDATE or INSERT,
on a transactional table, causing an implicit rollback.

Fixed by always flushing the pending event to reset the state
properly.
