Hi,

I using bind 9.7.3 as resolver in a slightly larger server farm with
some mail servers that use domain key validation.
If a try

# host -t TXT _adsp._domainkey.federalreserve.gov

bind dies with

May 26 19:59:02 resolv04 named[8237]: buffer.c:285: REQUIRE(b->used + 1
<= b->length) failed
May 26 19:59:02 resolv04 named[8237]: exiting (due to assertion failure)

This is reproducible and should only affected in 9.7.3. Can this be
possible?

Yes, UC Berkeley had 7 of 8 anycast servers die in the same way, and I do recall seeing exactly that query earlier in the stream. I think you're on to something, and I am looking into it further.
