Actually, OpenSSL does say why the handshake failed in this case:
AFAICT, OpenSSL reports that a system call has failed ("5" in "5/-1/0"
is SSL_ERROR_SYSCALL). Squid loses the details of that failure (e.g.,
what kind of system call error Squid has experienced), but we are almost
done improving that.
