calc undo fails?

calc undo fails?

What's the deal with undo in calc?  It's recently stopped working...
[just says "No further undo information available"]

I just tried it; it works for me.
What were you trying to undo?

Leaving calc and reentering it loses the undo history, but I think
that has always been the case.

It does if you leave calc with `calc-quit' ("q" or "M-# x"), that is;
'calc-quit' explicitly removes the calc-undo history.
If you change buffers or bury the Calc buffer some other way and then
reenter it, then the undo history will still be there.
Does the calc-undo history disappear without quitting Calc?
