I ask this, because not all systems possess dynamic-memory allocation (or at least "malloc" is not available on all systems).

Irrespective of the values of "writebuf1" and "writebuf2" in a), I see that everything works perfect.
So, there's got to be some internal-buffer that manages the complete ssl-packet, most probably instantiated via the call
BIO* BIO_new(BIO_f_ssl());

You should be able to produce the desired effect with
BIO_new_mem_buf() (twice) and attaching the resulting BIOs to each
other with BIO_make_bio_pair().<br>
