The absl container GDB pretty printers currently use a hardcoded version number for their fully qualified type, however this can become stale quite easily. A couple of options discussed in https://github.com/10gen/mongo/pull/11997 is to consider using a RegexpCollectionPrettyPrinter to match on the absl types, or point to the versions defined in the import script.

Per max.hirschhorn@mongodb.com, it would be better to tackle this work once there is more exhaustive testing for the printers.
