I have impression, that the callback is called from a non-Lisp thread, i.e. a thread that was not started by list, but was started by foreign code.
Is it known/supposed to work/fail? In CCL (and in general).
Not all Lisps support that mode of operation but it works for me on CCL + OSX. See <http://article.gmane.org/gmane.lisp.cffi.devel/1667> for more information and a small test to check whether your Lisp supports this feature. You might need to port it to Windows or use the pthread-win32 library. Let me know if that helps.
I just got a confirmation from the openssl-users list that OpenSSL doesn't invoke the callback from any threads not created by user, i.e. the non-Lisp thread theory is not valid. If you have any hints on how to determine the crash reason - it is very appreciated. BTW, I tried with CLISP - it doesn't crash. I've run the CFFI tests with CLISP, the result is similar to CCL, but the number of failures is a bit smaller. If you are interested, the test log is attached. Best regards, - Anton
