The second thought is that I've blown the stack size on the real device. I've not tried my changes on real hardware but I can't see why 0.9999999 would be special in this regard.


I can't recall anything in Bit's patches that would impact this and tan, but I've not looked at them for quite a while. I believe the function dispatch mechanism was changed but that would show up everywhere and my recent changes wouldn't alter this.

I confirmed that is wasn't low batteries via two methods. First I checked the Batt voltage 3.0 and second I ran the test with the USB cable attached which ensures that there is plenty of power.

How would one investigate the stack usage (or increase the stack size) on a real device? I don't own
an ICE debugger for the ARM cpu yet.

My previous flash version was 3870 and it worked(s) fine. I still have some real calculators with that flash version.

Thanks for the pointers. I can always flash the stock realbuild to omit this issue.

I love a good puzzle. Perhaps I will invest in a debugger so I can catch and back trace the anomaly.
