Look at the dump file for reload to see where things come from.  Also
everything Jeff said; you really want LRA.


I will try switching to LRA in a second step, but I think I need first to remove the old cc0...
BTW, in which way the LRA is better than IRA? Is there any benchmarks?

I would suggesting moving away from cc0 first. cc0 is an abominationand should have been abolished years ago -- the only reason is many oldports would break and nobody's taken the time to convert them or proposethem for deprecation.

While we try to keep the cc0-target paths working, they're not exercisedall that much and can easily break.
