To me it looks like something is out of sync, however with
such limited information I could not even begin to guess what.

I suggest checking that you dont have multiple gds32.dll clients
installed (or if you do that the correct one is being selected).

I also suggest checking the same read of the blob with the ISQL that
comes with whatever version of IB/FB you are using. See if the error
continues - that is; the errors are being reported by IB/FB so whether
the problem relates to IBO or IB/FB needs to be determined. If the
problem turns out to be IB/FB then send you question (with suitable
details) to ib_support.

Whereever you resubmit the question - please provide appropriate
details (versions, sql and components/programs being used etc).
