Comment(by nickm):

 Okay, that one's in write(), as called from sock_write, which lives in
 bss_sock.c.

 It calls writesocket (an alias for write()) as "write_socket(b->num, in,
 inl)". in and inl come as arguments from BIO_write(), and are passed in
 directly as the arguments of BIO_write.  Looks like that is called as:
 {{{
            i=BIO_write(s->wbio,
                    (char *)&(wb->buf[wb->offset]),
                    (unsigned int)wb->left);
 }}}

 If you still have that crash, can you also dump tls->ssl->s3 and
 tls->ssl->s3->wbuf ?
