I accidentally entered a divide by 0 from the keyboard and trying to recover, I noticed that the stack was not what I expected.

If I input:

2

Enter

3

Enter

0

[divide]

I get the temporary error message and on inspection, X,Y,Z,T are: 0,3,3,2

I don't believe that the 3 should be on the stack twice.

Thanks for reporting. Looks like a real bug. Repeatable also with 2 ENTER 3 ENTER 0 1/x. Seems the +infinity error isn't handled properly. We'll look into it.

Yes a bug in the stack lift management on error. I've committed a fix but haven't built it yet.
