Thanks! But we are providing SDK to our customers to retrieve extension from the certificates downloaded from Internet. We have no idea what OID will be used by the SDK users. Only SDK users will know what OID will be expected in a certificate.
OpenSSL should provide API to retrieve extension by OID.

The problem is that I need to get a customized certificate extension based on an OID. Until now, I cannot find a solution without dynamically calling OBJ_create(OID, NULL. NULL).

If you are using those API's you are adding new crypto. methods. Doing that after threading has started is not going to give good results with or without locking.

Well, the most likely fix is to make the “safely” wording be more vague, which I doubt you’ll like.
