Arduino+ESP-FACE Crash after face detection because of calls to free()
Posted: Fri Feb 28, 2020 6:01 am
Hi,
I am using the default CameraWebServer.ino sample that comes with Arduino-ESP32.
It works and detects my face only to crash after that upon calling `free` (see code below)
If I simply disable the calls to free (which I know I probably really should not do)
then the app works fine.

Code: Select all
box_array_t *net_boxes = NULL;
if(detection_enabled){
net_boxes = face_detect(image_matrix, &mtmn_config);
}
fr_face = esp_timer_get_time();
fr_recognize = fr_face;
if (net_boxes || fb->format != PIXFORMAT_JPEG){
if(net_boxes){
detected = true;
if(recognition_enabled){
face_id = run_face_recognition(image_matrix, net_boxes);
}
fr_recognize = esp_timer_get_time();
draw_face_boxes(image_matrix, net_boxes, face_id);
//This is where the app crashes
free(net_boxes->score);
free(net_boxes->box);
free(net_boxes->landmark);
free(net_boxes);
