[comp.sys.mac.apps] 4D Mover Bus Errors

pejacoby@mmm.serc.3m.com (Paul E. Jacoby) (04/26/91)

Is anyone else using the 4D Mover utility?  I've been working with 4th
Dimension 2.1.1 and have just started trying to use Mover to combine
some databases.  I am finding that everything I move results in a
composite database which will cause a Bus Error in some fashion.
  Two examples:
  (1) Moving some procedures from one database to another, the
  resulting database will Bus Error when I attempt to edit a procedure
  which has been moved.
  (2) Moving two databases into an empty database results in a Bus Error
  in the new composite database when I switch files in the User
  environment.
  (3) Moving all elements of one database into an existing database results
  in a Bus error in the composite database when I select a file which
  was moved. Selecting a file that was already in the original database
  causes no problems.

I have Macsbug installed, and have found that the Bus Errors will
generally cause the Mac to be totally incapacitated. In addition, on those
occassions when I can get an 'ES' to kill 4D, the Finder will
immediately implode with an "Illegal Instruction" error, and the machine
will hang.

I've talked to ACIUS, and they are "looking into it".  Is anyone else
having any LUCK with Mover?

Can't help you here; I assume you're talking about global procedures.
I've never had problems editing moved global procedures.  If this problem
happens with only one of your moved procedures, you might try doing a
copy-and-paste operation between the old database and a new procedure in
the new database; if it's with all of them, something definitely weird
is happening.

Before you switch files in the User environment, you need to set default
input and output layouts in Design.  The defaults from your original
databases aren't preserved in the move.

This is probably the same problem as (2), with the same solution.

Hope this helps!
