Espruino on ESP32

Hi,

I'm experiencing problems on the ESP32 when Storage.compact() is called, either explicitly or as a result of calling a write method.

In the last hour I compiled Espruino from a clone of the source on Github and using the example code in this issue, I'm getting the same Stack Overflow problem there described.

Sometimes instead of a stack overflow, I see a guru meditation error:

Guru Meditation Error: Core 0 panic'ed (LoadStoreError). Exception was unhandled

In the project I'm trying to work on, I'm storing configuration in Storage and updating settings a second time causes a crash.
