This may be related to the thing Edi mentioned the other day. Anyway, I start SLIME using Allegro 6.2 on Linux. Initially I'm in the directory where test-debug.lisp lives: ; SLIME: The Superior Lisp Interaction Mode for Emacs CL-USER> CL-USER> (compile-file "test-debug.lisp") ;;; Compiling file test-debug.lisp ;;; Writing fasl file test-debug.fasl ;;; Fasl write complete #p"test-debug.fasl" NIL NIL So far so good. Now I ,change-directory up one directory and try again. Which should fail since the file won't be found. But it doesn't just fail; in the SLIME repl window I get the following: CL-USER> CL-USER> (compile-file "test-debug.lisp") Error: Received signal number 11 (Segmentation violation) [condition type: SYNCHRONOUS-OPERATING-SYSTEM-SIGNAL] Restart actions (select using :continue): 0: Prompt for a different filename to compile 1: Abort handling SLIME request. 2: Abort entirely from this process. [Current process: repl-thread] [1] CL-USER(1): Typing Allegro commands (e.g. :cont 1) doesn't seem to do anything. C-c C-c gets me into sldb where I can use one of the ABORT restarts to get back to the main REPL. But this seems wrong. -Peter -- Peter Seibel peter@javamonkey.com Lisp is the red pill. -- John Fraser, comp.lang.lisp
