Bug#964577: sbcl: Memory fault, sb-kernel:output-ugly-object



Package: sbcl
Version: 2:2.0.5-1
Severity: normal

Dear Maintainer,
    
    I describe actions that lead to a "Memory fault" in sbcl.
    Same error happens with sbcl 2.0.6.59-e802114ba.
    No error with clisp and abcl.

   * What led up to the situation?

    in sbcl repl:

   (ql:quickload "cl-monad-macros")
   (in-package :cl-monad-macros)
   (with-input-from-string (in "1")
       (with-state-monad
           (run!
               (lambda (s) (cons (read in) in))
           in)))

   * What was the outcome of this action?
