Hello,

We don't use this TLS package at Wayport, but I have seen similar
errors with OpenSSL before in other applications.  I pulled the TLS
code and glanced through it.  It doesn't look like you have registered
the locking callbacks for openssl, which means any openssl calls are
not thread safe.  That's going to be a problem inside aolserver :-)

Check out InitOpenSSL() nsopenssl.c (in the nsopenssl module).  It
does all the basic stuff you need to get OpenSSL running in a
thread-safe manor.

Also:  http://openssl.org/docs/crypto/threads.html

If you 'info threads' and see other threads inside openssl crypto
functions this is almost certainly your problem.

HTH.

Here is a backtrace of the crash with 1.6 stable. Did you need it from head?
