Hi All,

Remember that few months ago was thread about random corruptions of
BLOB/text fields.

And nobody was able reproduce it.

!!! Yesterday Bart have sent us db and steps. !!! Wow :)

Ivan have found that secret is in
  SELECT with outer join on outer table with a BLOB field
   and then step on some records in this cursor.

THIS could corrupt underline table's BLOB.

FIXED. 

------------------
Now I wonder. 

Jon (jda) and others who have see this bug.
Please let us know if above conditions  can be found in your apps?


Again note, corruption of table did happens during SELECT which was going
just READ recs...
