It gets weirder. I commented the RC4 stuff out, problem disappeared but
obviously the self test fail (no kidding). Then I replaced the OpenSSL
calls with some unknown (slow) code I found on the 'net. The problem is
gone and all is fine (except performance, and unknown licensing).
What conclusions should I draw? I just happened to hide a problem in my
code that is still there? It's simple code. I have checked it a hundred
times. This drives me mad!
