commit 86f0b806812da8a53c25061acca500e0dcfb1103 Author: Yawning Angel yawning@schwanenlied.me Date: Tue Jun 14 04:40:36 2016 +0000
Bug 19406: OpenSSL changed the Thread API in 1.1.0 again.
Instead of `ERR_remove_thread_state()` having a modified prototype, it now has the old prototype and a deprecation annotation. Since it's pointless to add extra complexity just to remain compatible with an old OpenSSL development snapshot, update the code to work with 1.1.0pre5 and later. --- src/common/crypto.c | 21 +++++++++++---------- 1 file changed, 11 insertions(+), 10 deletions(-)
