Strange things happening with `E.compiledC`

Hi,

I tried E.compiledC on my Bangle 1 2v16 and see weird things happening. After "Resetting without loading any code", the following

var c = E.compiledC(`
// void init()
// int f()

volatile int a;

void init() {
  a = 0;
}

int f() {
  a++;
  return a;
}
`);

c.init();
setInterval(() => print(c.f()), 100);

gives me

Prior to that I ran code which wrote to RAM locations where it shouldn't have. So I rebooted and reflashed the firmware hoping it would reset the device and resolve the issues I see. Is there anything I can do? Its a bit scary to run code that might modify any RAM location at any point.

Thanks in advance!
