I have a problem with slime. When I give this expression to ecl in a terminal: (let ((*read-eval* nil)) (read-from-string "#.(car ")) it works correctly (reports and error and enters into the debugger): [pjb@mdi-development-1 localhost:10.0 |MDI| sources]$ ecl ECL (Embeddable Common-Lisp) 10.7.1 Copyright (C) 1984 Taiichi Yuasa and Masami Hagiya Copyright (C) 1993 Giuseppe Attardi Copyright (C) 2000 Juan J.

If I do the same at the slime REPL, the lisp connection is broken instead: CL-USER> 1 1 CL-USER> (let ((*read-eval* nil)) (read-from-string "#.(car ")) ; Evaluation aborted.
