The error says "an internal variable has a corrupted value". There is no way for a player to interpret that.
In general, whenever you see 'Assertion ... failed' in the log of a CTD, it means "something went terribly wrong". There's nothing you can do, just report it along with the circumstances.
Usually it's not really helpful to re-report a known bug just to say 'it's still there in revxxx'. However, after fixing a central bug, devs will ask the community to recheck all bugs of a certain category. In those cases you're more than welcome to re-report them.
