I'm getting a similar kind of panic.
The code is for the Espruino interpreter, and occurs when trying to set timers after about 150 iterations:
```
var count=0;
function blip() {
digitalPulse(21, 1, 15);
}
function start() {
setInterval(blip, 30);
}
start();
```
I have increase stack size in the vTask and also stack sizes in the menuconfig, but still getting the crash:
```

```
50 if (doWait) {
51 //Wait for whatever interrupt comes next... this should save some power.
52 asm("waiti 0");
53 }
```
How does an asm instruction call abort?
Any help appreciated!
