Re:[openssl.org #1867] About OpenSSL crashed in 0.9.8g

[zlgodguy via RT]

 hi :
  i got the assert information. d1_pkt.c(1284): OpenSSL internal error, 
assertion failed: 0

  i check the code. the assert occured in the red part.
  int do_dtls1_write(SSL *s, int type, const unsigned char *buf, unsigned int 
len, int create_empty_fragment)
    {
    unsigned char *p,*pseq;
    int i,mac_size,clear=0;
    int prefix_len = 0;
    SSL3_RECORD *wr;
    SSL3_BUFFER *wb;
    SSL_SESSION *sess;
    int bs;

    /* first check if there is a SSL3_BUFFER still being written
     * out.  This will happen with non blocking IO */
    if (s->s3->wbuf.left != 0)
        {
        OPENSSL_assert(0); /* XDTLS:  want to see if we ever get here */
        return(ssl3_write_pending(s,type,buf,len));
        }

    /* If we have an alert to send, lets send it */
    if (s->s3->alert_dispatch)
        {
        i=s->method->ssl_dispatch_alert(s);
        if (i <= 0)
            return(i);
        /* if it went, fall through and send more stuff */
        }


       any suggestions ?
