Suggestions on how to track a memory leak ...

[kolban]

I find that my app is leaking memory. I am executing a large amount of code (some mine, some third party) in a loop and I have a memory leak. I use the ESP-IDF esp_get_free_heap_size() after every 100 loop iterations and see that the free heap size is steadily decreasing. What I'm looking for is some guidance on how to debug memory leaks in an ESP32 environment. Does anyone have any thoughts on how to find lost heap memory?

FreeRTOS has pvPortMalloc / vPortFree, and you can trace calls to it with a tool: http://www.freertos.org/trace

Or using macros:

FYI I think I saw a merge request in the queue that fixes this.
