Your database is corrupted - some record has lenght different from declared
in RDB$FORMATS.
Usually fixing such error requires some special repairing actions to delete
it on physical level (i.e., gfix or gbak will not help).

Feel free to contact me about terms and conditions of repairing via
ak@...
