A call to PageAddItem(), made within _bt_pgaddtup(), is where this
failure seems to ultimately originate from. What we're missing here is
the reason for PageAddItem() returning InvalidOffsetNumber. That is
usually, though not necessarily, separately available within a WARNING
log message, which you haven't included here. Could you please let us
know if there is a WARNING that you didn't include just prior to the
ERROR?
