Hard fault crash when using HTTPServer: ESP32-C3

[dhalbert]

Running this test program, with a settings.toml containing valid values for CIRCUITPY_WIFI_SSID and CIRCUITPY_WIFI_PASSWORD, will cause a hard fault with a few minutes.

It takes around 1-5 minutes to restart in safe mode, though I have seen it run longer. No interaction with the HTTP server is needed. I simply restart code.py and wait.

import wifi
import socketpool
from adafruit_httpserver import Server
import time

time.sleep(5)
print("IP addr", wifi.radio.ipv4_address)

pool = socketpool.SocketPool(wifi.radio)
server = Server(pool, debug=False)

# port 80 will get EADDRINUSE due to web workflow
# Either IP adddress will cause a crash eventually.
server.start("0.0.0.0", 8000)
#server.start(str(wifi.radio.ipv4_address), 8000)

while True:
   try:
      server.poll()
   except Exception as e:
      print(type(e))

Either server.start() can cause a crash: the wildcard IP address or the actual IP address don't matter.

I have reproduced this only on a QT Py ESP32-C3. I cannot reproduce on a QT ESP32-S3, with no PSRAM.
