Description:
When comparing the catalog between database server and the model maintained in Workbench, everything works fine up to the moment the comparison really starts, then an error is raised. (It did work fine before!)

Exception = System.AccessViolationException
Message = Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
FullText = System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

How to repeat:
Just reboot machine, only start workbench, open the model, and do the compare.

Please let us know step by step what you did.

Standard steps: selection 'Database|Generate Catalog Diff Report ....'
=> Choose Live database server for left catalog
=> choose Model schemata for right catalog

Next: selecting a stored conection
Next: schema list is retrieved
Next: Schemata are displayed for inclusion/exclusion: exclude InformaitonSchema
Next: Retrieval is complete
Next: Comparision should happen, but error appears.
