Hi rahulcode60,

There is something missing between this and the previous log, there are logs missing.

The test vector shows that the test code is function openssl_eddsa_sigver. It perhaps looks like the following code path is triggered:

    } else {
            logger(LOGGER_WARN, "Signature verification: general 

error\n"); ret = -EFAULT; }

If so, the parser receives an answer that it did not expect. For that you can extend the logging message by

logger(LOGGER_WARN, "Signature verification: general error: %s\n", ERR_error_string(ERR_get_error(), NULL));

to get more information.

Ciao Stephan
