FunHouse Crash into the HardFault_Handler.

[slootsky]

CircuitPython version

Adafruit CircuitPython 7.3.2 on 2022-07-20; Adafruit FunHouse with ESP32S2
Board ID:adafruit_funhouse

Code/REPL

import adafruit_logging as logging
from config import config

logger=logging.getLogger('logger')
# logger.setLevel(config.get('loglevel',logging.WARNING))

import another

Behavior

Sometimes a soft reboot or the reboot button doesn't cause the problem, but using the power switch will.

Running in safe mode! Not running saved code.

You are in safe mode because:
CircuitPython core code crashed hard. Whoops!
Crash into the HardFault_Handler.

### Description

okay.  I get that there's a lot going on here, and a lot of it isn't perfect.  Some of it maybe even should generate a runtime error.  But getting it to crash into the HardFault_Handler seems unexpected :-)

I've attached all the files involved in this  (renamed from .py to .txt because that's what the uploader would accept).  [don't worry, secrets.py doesn't really have any secrets in it anymore]

Additional information

This is just about as minimal as I could get the code and still have the problem.

Any of the following will make it work again

• removing the logger import and code
• removing the from config import config
• removing the import adafruit_funhouse from another.py

I just tested with 7.3.3 and I get the same result there.

It does NOT occur with 8.0.0-beta0

If you put the from adafruit_funhouse import FunHouse into code.py instead of in another.py, does it work fine in 7.3.x?

If so, this might be a manifestation of #2687, but usually that doesn't cause a crash. The fact that 8.0.0-beta.0 doesn't crash may or may not reflect an 8.0.0-whatever fix.

[slootsky]

@dhalbert Yes. Moving from adafruit_funhouse import FunHouse to code.py makes it go away.

This of course means that I can't use FunHouse in another.py though.

What I've started doing is putting my main code in a secondary file that has the name of the project (eg co2monitor.py) and then importing that into code.py after doing some common setup and initialization.

Given that this seems to be another manifestation of #2687, this is fixed in 9.0.0-alpha.2 because long-lived heap was removed.
