I'm got a problem with named on FreeBSD-CURRENT/sparc64.
Up to 5 times a day it crashes with these messages:
27-Jun-2011 03:42:14.384 general:
REQUIRE(prev > 0) failed
27-Jun-2011 03:42:14.385 general: exiting (due to assertion failure)

The problem is still in latest system's bind:
# named -v
BIND 9.6.-ESV-R4-P1

This problem exists only on SMP sparc64 system. On my another sparc64,
with 1 processor, I does not have this problem.

I found a some similar problems on alpha and IA64, which was related
to problems with isc_atomic_xadd() function in include/isc/atomic.h.
But I don't understand that there may be incorrect for sparc64 and
this function was not changed for a minimum 4 years...

How can I help solve this problem?
