Package: libc6 Version: 2.19-18+deb8u3 Severity: important Dear Maintainer,
this is my first bug report so apologies in advance if I mess (have messed) something. IRRSI 0.8.17 started crashing with: "res_query.c:262: __libc_res_nquery: Assertion `(hp != ((void )0)) && (hp2 != ((void )0))' failed." Problem persisted on every restart of IRSSI after 2 - 35min at random. The condition that triggered it was "an IPv6 address was configured but no default route was available". Once IPv6 was properly working again, the problem dissappeared.
