Do I correctly understand that
- installed it
Segmentation fault is not seen if i don't compile ./config with -enable-weak-ssl-ciphers.Is it something I am missing or some more options needs to be provided to ./config ?ThanksSatyamOn Mon, 26 Oct 2020 at 20:21, Dmitry Belyavsky <beldmit@xxxxxxxxx> wrote:It has nothing to do with the ciphers command...On Mon, Oct 26, 2020 at 5:18 PM Satyam Mehrotra <satyam226@xxxxxxxxx> wrote:Dear Dmitry,>>Are the /usr/local/lib64/libssl.so.1.1 and /usr/local/lib64/libcrypto.so.1.1 the same libraries that were built by you?Yes, they are samegdb openssl core.50178
