Summary: Stack Overflow Twice Causes Segfault

Initial Comment:
Causing a stack overflow twice in a row leads to a
segfault in clisp 2.33.2 on x86 Linux from Gentoo
ebuild.  gcc is version 3.3.5, and glibc is version
2.3.4.  My "CFLAGS" is '-mcpu=i686 -O2 -pipe'.  Gzipped
core file is attached.  Note that this error does *not*
happen with a clean, debug-enabled build.  Should I
send this bug report to the Gentoo ebuild maintainer
instead?


This is how I produced the problem:

$ clisp -q -q

[1]> (defun f (n) (if (zerop n) 0 (f (1- n))))
F
[2]> (f 10000)

*** - Program stack overflow. RESET
[3]> (f 10000)
Segmentation fault (core dumped)
