asmodai> Patch is in CURRENT.
I've already found your patch applied to
src/contrib/bind/lib/dst/support.c. It's now revision 1.1.1.4, right? :-)
asmodai> So if you could test it? :)
I tested with this your patch, and applied to 4-stable. I've rebuild
libbind, then named/nsupdate.
Good news: nsupdate work fine. It seems that first bug is resolved.
Bad news: named still dumps a core (second bug is not resolved) when
I'm deleting an A RR from my dynamic DNS zone.
Attached below is an output of gdb. There is a gap between #2 and
#3... how do I check what functions are called between free_rrecp()
and ns_panic() ?
