Guru meditation error when trying threads

[rvandam]

I am trying to run the new Lora example in a thread. I use the example used from here:
https://forum.pycom.io/topic/526/lopy-nano-gateway-extended-timeout-and-retry

Without threading everything works fine

This leads to this error:

PYB: soft reboot
Guru Meditation Error of type LoadStoreError occurred on core 0. Exception was unhandled.

I have received the same crash numerous times over the last week, basically anything that involves interrupts or threads.

I have just implemented a press button debounce / handler using the pin interrupt feature, this works fine as long as nothing else is running, but crashes the system otherwise.

I'm glad that I am not the only one seeing this !!
