> if (ptr!= NULL) free(ptr); That shouldn’t be necessary for OpenSSL. If you find places where it is, please open an issue. ➢ BTW, "can handle" should explicitly say what happens. Perhaps use the C library text, which says: If ptr is NULL, no operation is performed. That is the wording we use. -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
