In the last few -current releases, I've had the message
Malloc warning: free(): junk pointer (too high)
at system startup. It comes from mountd, and it's wrong: the address
being freed is in the text segment.
Is this intentional? Should free(3) even try to accept this sort of
behaviour? In any case, it's easy enough to fix:
