Behavior
The crash happens after it has run for a while. One to 12+ hours after start.
REPL stops and disconnects from Putty without comment.
The board has crashed.
Minutes to hours later I then close Putty and then reopen Putty to get the crash notification.
It is like it just waits for me to reconnect Putty to give me the bad news.
Auto-reload is off.
Running in safe mode! Not running saved code.
You are in safe mode because:
CircuitPython core code crashed hard. Whoops!
Hard fault: memory access or instruction error.
Please file an issue with your program at github.com/adafruit/circuitpython/issues.
Press reset to exit safe mode.
Press any key to enter the REPL. Use CTRL-D to reload.
