I try to compile MicroPython v1.17 (tag v1.17) with ESP-IDF4.2 and ESP-IDF4.3 and ESP-IDF master branch
There is memory leak in latest ESP-IDF releases.
Be careful.

MicroPython v1.17-dirty on 2021-09-17; ESP32 module with ESP32
Type "help()" for more information.
>>> from gc import mem_free
>>> print("mem_free()", mem_free())
mem_free() 109488
>>> 

ESP-IDF4.3 and ESP-IDF master branch
