Memory leak somewhere #15
Description
There seems to be a memory leak.
Where? Library or in PSRamFS_Test.ino?
I did not audit PSRamFS_Test completely.
I did change all the ESP_LOGx(...) to Serial.printf and fixed the formatting.
I changed it to run in loop() instead of setup() with a halt at the end. I kept setup code in setup. Not much of that.
I tried a Arduino Nano ESP32 (16M flash, 8M PSRAM) and a Espressif ESP32-S3 De Kit N8R8 (8M flash, 8M PSRAM)
The leak is in both.
The biggest annoyance is that the leak is different for each iteration.
It could be as simple as an unpaired create/close. Like I said, didn't do a complete audit of PSRamFS_Test.ino and didn't create a sketch from scratch with more limited use of the library.
The leak is from 0 to 440 byes. Varies each run, each pass through loop.
