我尝试在Debian 6.0上安装SBCL，我试图运行它以获得一个lisp解释器。当我运行它时，我得到以下输出：
#> sbcl
This is SBCL 1.0.40.0.debian, an implementation of ANSI Common Lisp.

fatal error encountered in SBCL pid 20335(tid 3085240000):
premature end of core file
Welcome to LDB, a low-level debugger for the Lisp runtime environment.

致命错误是我的错误，我无法加载像quicklisp这样的文件，所以看来我的安装已经破了。我尝试删除它并使用apt-get重新安装它，但得到了相同的结果。
此错误意味着什么，我该如何解决？
