Yes that is confirmed from our side also on multiple units , esp8266 with AR on MM seems to be fine for comparison

While I've opened PR #4222 to fix the general case issue, technically this is already fixed by 26a4753.

@spblat We have tested on esp8266 4mb and 2mb , AR is working fine without crashes , please test the same and close this .
