Re: [mdb-dev] Segmentation Fault

[<br...@br...>]

I'm currently working on these issues.  What happens is you have a
table that has at some point had columns added or deleted from the
table.  When this happens, Access does not go back and retouch the
rows, it simply updates the table definition and moves on.  Thus the
number of columns recorded for the table doesn't match the the number
stamped on the row.  So what does this have to do with your problem?

version 0.5 largely ignored the issue and that works for a certain
subset of column add/deletes, but can give screwy results in other
cases (values appearing in the wrong column or corrupted for
instance).  The CVS version is attempting to take a more correct
approach, but isn't quite there yet.

I have a yet-to-be-checked-in patch to handle JET4 databases, but I'm
not quite ready with JET3 (but very close).  I hope to have it all
ready by this weekend.   If you're interested in testing, I'll let you
know when it's commited.
