Subject: Fix a bug in usage of SSL_set1_groups_list()
X-Git-Tag: tor-0.3.3.11~16^2^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=46796623f995c5b63d5cfbda1a038d9f6158ec90;p=thirdparty%2Ftor.git

Fix a bug in usage of SSL_set1_groups_list()

Apparently, even though the manpage says it returns an int, it
can return a long instead and cause a warning.

Bug not in any released Tor.  Part of #28399
