Description
An frm file found "in the wild" had 0x2b as its 4th byte. This "works" fine in MariaDB <5.5.33 but causes crashes in MariaDB 5.5.33. Changing this byte in the .frm file to 0x2a allows the table to be used in MariaDB 5.5.33, but the first use gives this warning:
| Note | 1194 | Zerofilling moved table ./test/kb3_domains |
|
It is not clear how this .frm file was originally created, but I am assured that it was generated by MariaDB.
