Additional Information:
I can reproduce the error by including this short code into any place of the engine
init function:
{ RSA *rsa = NULL;
rsa = RSA_new();
RSA_free(rsa);
}
When I include this code in another engine function that is loaded dynamicaly
everything works still
fine. Is there a possibility to run this code in the init function correct as well?
