an error, asserts server In case of a fatal error during filesort in find_all_keys() the error was returned without the necessary handler uninitialization. Fixed by changing the code so that handler uninitialization is performed before returning the error. mysql-test/r/delete.result: Added a test case for bug #31742. mysql-test/t/delete.test: Added a test case for bug #31742. sql/filesort.cc: In case of a fatal error in find_all_keys() do not return before doing the necessary handler uninitialization steps.
