looking for information on generating RSA key

[Kavita_Jain]

Hello,

I am a novice OpenSSL library user. Currently I am implementing code to 
generate a RSA key pair. Here
is a part of my code:

        _time_get(&tim);
        RAND_add(&tim,sizeof(tim),0);

        pMiSslCtx = MiSslInitEx( TLSv1_method(), true );
 
        rsa=RSA_generate_key(key_len,RSA_F4,NULLcb,NULL);


my key_len is 2048. 

The code crashes in RSA_generate_key() function call, more particularly in 
probable_prime(). I am not sure what 
I am doign wrong here. Any help would be highly apprecaited.

Thanks
