If alignment of "buf" is the issue, then yes, a suitable union
would be an alternative to using malloc.  We could make the union:

    union {
	unsigned long long dummyl;
	ossl_uintmax_t     dummym;
	char              *dummyp;
	char buf[DATA_BUF_SIZE];
    } d;

just in case that's what it takes for the required alignment.  But,
OPENSSL_malloc() should do the job simply, without such hoop jumping.

Either way, the OP should confirm that aligning "buf" solves the
reported problem.
