Hi,
Using the bind backend as a slave on OpenBSD 3.3, with gcc 2.95.3, causes
pdns_server to segfault in ZoneParser::eatLine at
backends/bind/zoneparser2.cc:236 . Any clue on how to get this fixed
would be greatly appreciated.
Here are the details:

Inspecting the core (I've build pdns-2.9.11.tar.gz, with a tiny patch
to pdns/common_startup.cc (see yesterday's post by me), with
gmake CXXFLAGS='-pthread -Wall -O0 -g -fno-default-inline'
) yields:

Anybody has a clue on how to get this fixed? Would it be of any use
if I build with a more recent gcc? Or is something else wrong here?
Should I give more information?
FYI: When running with
zone "mdcc.cx" {
type master;
file "/usr/local/etc/bind/mdcc.cx";
};
in named.conf and no slave setting in pdns.conf, things work
reasonably smooth.
Any help would be greatly appreciated.
Bye,
Joost
