Updating BLR fields directly is not a usual thing to do,
though gbak and a few of the other utilities do it. BLR
(Binary Language Representation) is a binary coded relational
statement, or in other words, gook. By convention, a BLR
string starts with the version number which should be 4
or 5. The "expected 4, encountered 98" part of the message
says that the string you stored started with a 98 ('b') (hex
62).

Are you sure it's exactly the same?

I don't know exactly what's going on but I doubt that it's a
bug. May I ask why you want to update that field?
