:-)

You won't find that in the source - it's an example to show what your
app (or MS ADO or similar) might be doing wrong. If the actual data
being read in the SQLGetData call is larger than max_longvarchar_size,
it'll overflow szData.

I guess one answer might be to cap the size reported by SQLGetData to
whatever the column size is, but I'm pretty sure that will likely break
things for other people (though it should be fixable by tweaking
maxlongvarcharsize).
