plot2d failed to plot too many discrete points

Sorry for not enough info.

I generated some sequence similar to an oscillating signal, in
bfloat; haven't change fpprec though.  Then FFT it, take the real
part and try to plot it.  It failed, said control stack
exhausted.  I executed that in Emacs SLIME, if this is relevant
to stack size please tell me.

P.S. Your example failed for me too.  I ran `maxima' from command
line, version being the one in Arch Linux repo.  Error message:

--8<---------------cut here---------------start------------->8---
INFO: Control stack guard page unprotected
Control stack guard page temporarily disabled: proceed with caution

Maxima encountered a Lisp error:

 Control stack exhausted (no more space for function call frames).
This is probably due to heavily nested or infinitely recursive function
calls, or a tail call that SBCL cannot or has not optimized away.
--8<---------------cut here---------------end--------------->8---

I know the process, but a stack overflow is not likely to bring
up a lisp debugger for me.
