It sounds as if your database has exceeded 4Gb in a single file,
causing the byte-offset value to roll over. The result is that
something has written an index page (7) on page 0 which should
be the header page (1). The header page then got written back
over the index page - it gets written a lot. Gbak was following
an index and discovered the error.

Gbak uses only system indexes - indexes on system tables. Since
it reads all of every data table, it uses only natural scans of
user data. So, you've had the bad luck to corrupt a system index.
The tools distributed won't fix that. With luck you've got a recent
backup and can move forward from it. Otherwise contact IBSurgeon
or me.
