Oh dear, sounds like you're in a right pickle.
Don't forget to call this first:
SSLeay_add_all_algorithms();
It fills out some structures in SSL library that may be the cause of
your problems (I had the same problems as you, and this fixed it, after
much debugging).
There's no need to call RSA_new() as the RSA_generate_key() allocates
the memory for you.
I am using ssl 0.9.0b, but I think it's more or less the same as
openssl.
Good luck!
Tat.
It fills in some static data in the crypto lib and may be the cause of
your problem.
