Comment (by fbissey):

 Just for your information leif this is what sbcl says:
 {{{

 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.

 PROCEED WITH CAUTION.

 Automatically continuing.
 To enable the Lisp debugger set *debugger-hook* to nil.

 }}}
 Note that with sbcl the crash is rather graceful in that maxima is still
 running.
