[cl-ppcre-devel] Potential bug in 1.0.13: LDB prompth when using CL-PPCRE.

[Victor Kryukov]

Hi SBCL developers,

The following program brings LDB> prompt for me.

sbcl-bug.lisp
-----
(require 'asdf)
(asdf:oos 'asdf:load-op 'cl-ppcre)
(funcall (cl-ppcre:create-scanner "test") "This is a test")

victor at esculap:~/src/sbcl-1.0.13$ sbcl --no-userinit --no-sysinit
--load ../lisp/sbcl-bug.lisp
This is SBCL 1.0.13, an implementation of ANSI Common Lisp.

Welcome to LDB, a low-level debugger for the Lisp runtime environment.

I'm using Ubuntu 7.10 on x86-64:
victor at esculap:~$ uname -a
Linux esculap 2.6.22-14-generic #1 SMP Tue Dec 18 05:28:27 UTC 2007
x86_64 GNU/Linux

SBCL is 1.0.13 manually compiled from sources with :SB-THREAD enabled.

CL-PPCRE is Edi Weitz's library, version 1.3.2 (ASDF-installable,
http://weitz.de).

I'd be happy to provide more info if needed.
