	Firstly.  Why are you still running a RC?

	Secondly the are completely different errors.

	Yours is a unbalanced number of isc_mem_put() / isc_mem_get()
	at a given size.  More puts than gets.  In your case I would
	upgrade to BIND 9.2.4 and see if the error reoccurs.

	The other is that the memory pointed to by name has the wrong
	magic number at the start.  BIND 9.3.1 has a possible fix.
	BIND 9.3.1beta1 should be out shortly.
 
	In general errors like this should be reported to bind9-bugs at isc.org
	along with a stack backtrace so we have some context to work with.
	Without a stack backtrace we are working completely in the dark.

	Note: 'named -u' disables writing cores as a side effect of the
	setuid() call.

	For FreeBSD you can stop this side effect with:
		sysctl kern.sugid_coredump=1
