Taking my cues from your patch, I looked at v4.0.2.

Below is the extract from t2p_process_ojpeg_tables() which I referred to:

3159 t2p->t2p_error = T2P_ERR_ERROR;
3160 return(0);
3161 }
3162 if(!TIFFGetField(input, TIFFTAG_JPEGPOINTTRANSFORM, &pt)){
3163 TIFFError(TIFF2PDF_MODULE,
3164 "Missing JPEGPointTransform field in OJPEG image %s",
3165 TIFFFileName(input));
3166 t2p->t2p_error = T2P_ERR_ERROR;
3167 return(0);
3168 }
3169 }
3170 if(!TIFFGetField(input, TIFFTAG_YCBCRSUBSAMPLING, &h_samp, &v_samp)){
3171 h_samp=1;
3172 v_samp=1;
3173 }
3174 if(t2p->pdf_ojpegdata != NULL){
3175 _TIFFfree(t2p->pdf_ojpegdata);
3176 t2p->pdf_ojpegdata=NULL;
3177 }
3178 t2p->pdf_ojpegdata = _TIFFmalloc(2048);
3179 if(t2p->pdf_ojpegdata == NULL){
3180 TIFFError(TIFF2PDF_MODULE,
3181 "Can't allocate %u bytes of memory for t2p_process_ojpeg_tables, %s",
3182 2048,
3183 TIFFFileName(input));
3184 return(0);
3185 }
