alter table `t5` add primary key(`a`(220));

Looks like a bug in error handling, an assertion when dropping the table.
[12 May 2010 10:42] Marko Mäkelä
For the documentation: The error handler of fast CREATE INDEX forgot to reset the error state of the transaction before attempting to undo the failed operation.

Noted in 5.1.48, 5.5.5 changelogs.

For InnoDB tables, the error handler for a fast CREATE INDEX did not
reset the error state of the transaction before attempting to undo a
failed operation, resulting in a crash.
