Hi,  
  
A bit more testing and I think I can guess why Tim sees it work or not work some time.  
  
Note that below that result is correct for 2 raisedTo: 64.  
  
Somewhere walking back up the stack it loses the value.  
  
So ok:

One level up, still ok:

Still ok

Still ok  
  
![image.png](cid:1cd855677434be7788a5cd38ed2c6e083983d7d5 at infomaniak "image.png")  
Still ok  
  
![image.png](cid:15c86f7732c72bb179bfb2dabc80204a73ade6df at infomaniak "image.png")  
  
But then somewhere between here, and actually printing the value we lose it.  
  
I don't get why.  
  
Thanks
