I have to admit, it's not an easy one for me, since it only occurs in
certain circumstances that probably not everybody uses.

I didn't find anything to point me in the right direction. The only thing
I found was that somehow the TIB_Row.PSQLDA.sqln value is bigger than the
number of items found in the TIB_Row.PSQLDA.sqlvar property. This seems to
be the reason why there's an AV error in TIB_Row.SysClearBuffers method
when the code is walking through the PSQLDA.sqlvar array, by using the
PSQLDA.sqln value as a counter(and I know that's how it's supposed to be,
since they are supposed to match). I tried using the Length function to
count the number of elements in PSQLDA.sqlvar and assign it to PSQLDA.sqln,
but no success.

If I would have the time to study in more detail the source code of IB
Objects, I would try to dig deeper, but unfortunately the time is not on my
side right now.

Have a nice day.
