Matt Complete mis-read on my part, there is nothing wrong with SSL_new() and BIO_s_mem(). I neglected to recall I was debugging a unittest with a client thread was using the simpler bio_s_connect() to test our non-blocking server. The debugger was showing us the other thread. -- thanks much. > -----Original Message----- > From: openssl-users [mailto:openssl-users-bounces at openssl.org] On > Behalf Of Matt Caswell > Sent: Saturday, August 06, 2016 4:48 AM > To: openssl-users at openssl.org > Subject: Re: [openssl-users] Trouble with BIO_s_mem() and SSL_new() on > OpenSSL-1.1.0-pre7-dev > > > > On 06/08/16 02:32, Jim Carroll wrote: > > We have a non-blocking windows app that we are migrating to from > OpenSSL > > 1.0.2i to 1.1.0-pre7-dev.
