Package: sphinxsearch Version: 2.2.11-1.1 Below is a crash dump I get when running searchd.
I am running `Linux 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u1 (2017-06-18)
x86_64 GNU/Linux`.
I don't know how to reproduce but it happens often enough, I've been
running `/usr/bin/searchd --nodetach --console --logdebugv` in a while
true loop and it is not regular at all but I can see it happens ever 30s
on average (no pattern here).
