Thanks for your efforts, but the new workaround : http://git.infradead.org/ocserv.git/commit/6f4f60db5afaaeadfbabb648ccdb5991b15dfc00 causes the worker process to crash on my box (debian wheezy) with this error : Aug 25 05:58:43 XX kernel: [61217.330915] ocserv-worker[32574]: segfault at 10e8 ip 00007f9d53733960 sp 00007fffc4752b78 error 4 in libgnutls-deb0.so.28.30.6[7f9d536dd000+104000] I am using libgnutls28-dev to compile ocserv : root at XX:~# apt-cache show libgnutls28-dev Package: libgnutls28-dev Source: gnutls28 Version: 3.2.15-2~bpo70+1 Installed-Size: 2800 Maintainer: Debian GnuTLS Maintainers <pkg-gnutls-maint at lists.alioth.debian.org> Architecture: amd64 Replaces: gnutls-dev Provides: gnutls-dev Depends: libgnutls-deb0-28 (= 3.2.15-2~bpo70+1), libgnutlsxx28 (= 3.2.15-2~bpo70+1), libgnutls-xssl0 (= 3.2.15-2~bpo70+1), nettle-dev (>= 2.5), libc6-dev | libc-dev, zlib1g-dev, libtasn1-6-dev (>= 3.1), libp11-kit-dev (>= 0.20) Suggests: gnutls-doc, gnutls-bin, guile-gnutls Conflicts: gnutls-dev I dont know if it is related or not but libgnutls28-dev is a backport for debian wheezy. the stable package libgnutls-dev is version 2.12.20 and can not be used to compile ocserv. let me know if you need more information.
