installing OpenSSL 1.1.1 on RedHat 6.x

Hi Tom,

So from what you say, you can run  an OpenSSL built on RedHat 6.6 on a
RedHat 6.6 server.
But you cannot run that build on RedHat 6.5?

Is the OpenSSL version being used built on the platform that it is run on?
You cannot use a version compiled on a newer platform in an older

We have a customer who is running our product on a RedHat 6.x server.
Our product uses OpenSSL 1.1.1 to handle secure connections.

Initial testing by the customer is showing segmentation faults in OpenSSL
during the handshake process.

We have successfully tested our product on CentOS 7.x servers.  

I know that RedHat certainly doesn't ship recent versions of OpenSSL  for
RedHat 6.x.  However it is still possible to install later OpenSSL versions
to run side-by-side the system installation.

What I'm wondering is, would there be a  technical reason why OpenSSL 1.1.1
would not work correctly on a RedHat 6.x system?

For the record the customer has tried with OpenSSL 1.1.1g and 1.1.1k with
similar results.

Many thanks,
