Hi,<br>
<br>
I'll take a look and see if I can reproduce, but a couple of extra
questions:<br>
* Did this work with 5.7.22? MySQL 5.7 links yaSSL statically, and
mixing this with your own link to openssl would always have a big
chance of causing issues, but version updates to yaSSL or OpenSSL
could have triggered the actual error.<br>
* Have you tested the build without linking to openssl (this would
mean you get all ssl functionality through libmysqlclient and
yassl)?<br>
<br>
Also note that if it is an option for you, MySQL 8.0 uses dynamic
linking with OpenSSL, so this would no longer be a problem.<br>
<br>
