Dear Devadatt
The "generation possible" status is the worst case you can get,. The only way to deal with it (as far as I know): use debug and replace and remove report from CG50 completely (e.g. set del flag). It it quite long ago that this status has happened. It comes up very rarely. To my knowldege: this is nothing related to the specification; So sorry. No additional help possible.
