On which platform?

At the end of the configure run it displays a lot of info about what it found
and thus what features that will be used/enabled in the build. Does that
summary state that it has SSL support enabled? It should even say "OpenSSL" on
that line.

So you say it still uses OpenSSL without "depending" on it ? Wouldn't that
imply that you're actually using another build/library than the one you
checked?

That's an error code returned from OpenSSL's SSL_connect() function. I presume
that happens because something bad happens.

I trust "same" means SSL connections to the same server. I think that would
hint on a problem in the OpenSSL version you run here. Either a version
dependent problem or an architecture dependent problem as by your wording I
assume the problem isn't on Linux or Solaris but on something else.

Yes, and that is shown both in the configure summary and in `curl -V` output.

I don't know. OpenSSL seems to detect a problem and return that error. I don't
know why...
