Thank you for this. Following the traces, it seems everything went fine in the
libssh initialization.
But it seems this lead to an error when initializing the threads in mariadb. As
the comment in [1] point out, the library initialization can fail only because
of issues when initializing threads or due to out of memory.
I'll have to debug this further, but it is intriguing for me why this happens
only when using OpenSSL.
