This looks like it was deliberately corrupted. Line pointer 255 is an
LP_REDIRECT, line pointer, while line pointer 256 and 257 are
LP_UNUSED, which should never happen.
The ascii string "blablahblah" has been overwritten at byte offset
1040 (from the beginning of the page). I would take a closer look at
what those tests do. Either the problem is in the tests, or your
database is haunted, which is outside my area of expertise.
