There is an issue where an optimised OpenSSL function causes a buffer overrun in 64-bit Windows builds and terminates the process (this is why the buildbots aren't getting very far right now). I suspect it may be a compiler issue, but for now I'm disabling the optimised function. This issue is a reminder to myself to re-enable the function when we have a fix. I'll follow up with the compiler team and possibly the OpenSSL team separately.

I did not get a helpful response from the compiler team, so the optimized function will have to stay disabled for 3.5. Moving this to 3.6 in the hope that we can figure it out by then.

Buildbots look okay with this now, so considering it closed.
