BUG#24855 - Crash mysqld 4.1.21 with corrupted tables
BUG#24855 - Crash mysqld 4.1.21 with corrupted tables

Accessing fixed record format table with crashed key definition results
in server/myisamchk segmentation fault.

This is fixed by refusing to open such tables. Affects MyISAM only.
No test case, since it requires crashed table.
