Yeah, it's a double free(3).  If you comment out the calls to free(3) 
the bl_list, r_tmp, pnode, and fnode (and their _tmp counter parts), 
you'll prevent the double free(3).  I know that's not the correct 
solution, but since rcorder is such a short lived process with a 
limited role (albeit an important one), I think it'd be an okay 
solution for now.

!  Bugger I thought this was specific to my environment since I don't 
have rpcbind in my rc.d tree.  obrien (or whoever has assumed 
maintainership, couldn't find any references to someone), since you 
originally imported this code, do you have any plans on importing a 
recent snapshot of NetBSD's code?  I've noticed that they've ANSIfied 
the code, though there aren't any changes that are significant or worth 
while beyond that.

Regardless, for the time being, I have put ntpdate back in rpcbind.  -sc
