The patch you attached previously is v1; I submitted v2 after review by
Stephan Mueller. I additionally attach it here below.

IMO, the preferable fix depends on your future plan.
If you plan to continue using both ANSI X9.31 DRNG and DRBG - I agree with the
patch suggested by Artem Savkov.
If you plan to reduce using ANSI X9.31 DRNG and use DRBG more widely - I
suggest my patch.

Best Regards,
Kirill
