[gnutls-devel] crash inside of wrap_nettle_rnd?

[Jason A. Donenfeld]

Hi folks,

I'm getting a crash in weechat, and after some debugging, the
maintainer of weechat told me to complain here. I've put all the info
in this gentoo bug: https://bugs.gentoo.org/show_bug.cgi?id=501078 .

Here are various backtraces:
