>Thread 7282896l tries to lock same object twice.
This was not cause of problem. I saw crash after one lock on another thread.

I could create the C code to reproduce crash. (reproduce.zip)
But strangely, I couldn't crash main.exe if it was built with
http://www.openssl.org/source/openssl-0.9.8h.tar.gz (same version)

I compiled openssl with "config -dCygwin" and "make". (I needed to fix
one broken link in Include dir though)
