Yep, see

Ismail, aka cartman in IRC, reported it a while back and has narrowed
it down to

Even further debugging shows following code from symbol.c is
miscompiled
at -O2 :
==========================
#include "lispbibl.c"
LISPFUNNR(keywordp,1)
{ /* (KEYWORDP object), CLTL p. 170 */
{var object obj = popSTACK();
VALUES_IF(symbolp(obj) && keywordp(obj));
}}
==========================
Bruno do you think you could help me to get this code standalone
somehow
so I can report a gcc bug?

So I hope that Bruno can figure it out and fix.

Carl Witty played with the optimization flags and got it to work (he
reported the problem on debian testing x86 and also gave some details
in the 2.9.alpha0 thread). I will add that info to the ticket soon.
But there is no clean way to automate that workaround yet, so bumping
it back a week or two and hoping from an upstream patch is the way to
go. You might want to let Sam & Bruno know that we are counting on
them :)
What we can do is offer clisp-2.43.spkg as experimental, so that
people who want to install FriCAS or OpenAxiom can install it and
cross their fingers that it works.
