Example causes crash on esp32

[ryleymcc]

Hello all, I'm using an esp32 feather huzzah from adafruit. I'm trying to run one of the examples called "group_sub" but I'm getting repeated crashes on all my esp32's. The other examples I've tested work fine. It seems to be something going on with the group message handler as every other example works? In the code I'm running I haven't even entered my wifi credential or adafruit io info but it shouldn't crash. My problem is probably obvious to someone I would just assume that the examples have been already proven to work.

Here is the report I get from the serial port.

Please try installing the ESP32 stack trace decoder, and pasting the output from there: https://github.com/me-no-dev/EspExceptionDecoder

That will help tell us where it's getting stuck.
