[Pdns-users] PowerDNS (2.9.22) crash with signal 8 (floating point exception)

[Dmitriy Lyfar]

Bert,

BTW, I have compiled pdns from sources (2.9.22, the last one) as following:

./configure --prefix=$PWD/distr --enable-static-binaries --enable-shared=no
> --enable-verbose-logging
> make
>

And replaced /usr/sbin/pdns_server with new executable. All works fine. Not
sure I understand what is happening.
