   I would prefer to implement Leo's suggestion.

Looking at the code, the warning is a false positive, as in actual 
execution the index never goes to 5 (e.g. YoungFreeCSet does not have 
sub-items afaict), and the _work_items != NULL check prevents it from 
being an actual issue.

I am open to making GCC happy by extending the array *if* the manual 
check/assert does not help, which gcc very likely does not recognize, too.

Thanks,
   Thomas
