M-x calc
2n
0
kc

I.e. try to calculate the binomial coefficient of (-2 0). This doesn't
work and calc suggests you give it more time:

Computation got stuck or ran too long.  Type `M' to increase the limit

So do

M
kc

and repeat a couple of times.

Once `max-lisp-eval-depth' hits 64000 emacs crashes.

I can send a backtrace if necessary.

Well, you dug up an old bug and turned our attention to it, so in a sense you did bring about the resolution!

Patch pushed and bug closed (again).
