Ah yes, I moved the 8077982 in front of the colon when it's actually part
of the bug description i.e. RFR: 8081315: 8077982 giflib upgrade :(

I'm not sure about this myself; it's much like the IOException that
can be thrown from closing a Java stream. As far as I can see from [0],
it would throw an error if it fails in reading the GIF terminating block
or deallocating used memory.
